Lead-free cable glands

More information on RoHS & REACH

The use of lead in commercial and industrial products has fallen sharply in recent decades. Until now, however, small amounts of lead were still permitted in a few areas of application. For example, the RoHS Directive currently still allows up to 4% lead in copper alloys such as brass, the material used in SKINTOP® and SKINDICHT® brass glands, as an exception for electronic products. However, this exception officially expired on 21 July 2021. The EU Commission has yet to take a decision on its extension. The outcome is still uncertain.

As early as 2020, LAPP was the first manufacturer in the world to present cable glands in a lead-free brass version. Together with us at an early stage, take the opportunity to rely on sustainable lead-free cable glands that can be used in the long term.

What is a lead-free cable gland?

Lead-free cable glands are also cable glands. The only difference is that they are produced without the common two to four per cent lead content as an additive in brass, which is allowed according to the RoHS Directive.

Lead-free cable glands and lead-free cable gland accessories from LAPP can be identified by the designation “LF” (lead-free). This means that you get our accustomed and current cable glands, such as the SKINTOP® MS-M and the MS-SC-M or our lock nut SKINDICHT® SM-M, with the same performance, also as lead-free variants. New to our range, you can now also get SKINDICHT® BL-M blanking plugs, SKINDICHT® MR-M reducers, SKINDICHT® ME-M enlargers, SKINDICHT® MA-PG/M adapters and SKINDICHT® SM-PE M lock nuts with claws in a lead-free variant.

Lead-free cable glands

Since its launch just over a year ago, we have made lead-free brass an integral part of life at LAPP, successfully mastered the challenge of alternative materials, and will gradually supplement other product families to include lead-free versions for you.

As the global market leader for integrated cable and connection solutions, we didn’t wait, but we were the first manufacturer in the world to establish cable glands made of lead-free brass early on and to this day have expanded our lead-free product portfolio for you.

As always proactive rather than reactive – so you can react early and sustainably to upcoming changes.

What are REACH and RoHS?

In order to protect people, animals and the environment, various laws such as RoHS and REACH regulations stipulate the use of chemicals, their restrictions and areas of application. The REACH directives also determine the permitted lead content in copper alloys.

POP – Directive (EU) No. 2019/1021 of the European Parliament

What is REACH?

Commonly referred to as the REACH Regulation, “Regulation (EC) No. 1907/2006 on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH)” has been in force since 2007 and is one of the most stringent chemicals laws. The regulation was issued in order to improve the protection of human health and the environment against the risks that can arise from chemicals, while at the same time increasing the competitiveness of the EU chemical industry.

In 2018, lead was added to the list of substances of very high concern (SVHC list: Substance of Very High Concern). According to Article 33 of the REACH Regulation, this results in an information obligation along the entire supply chain for all materials containing lead, correspondingly also brass with lead content. If semi-finished products or other products have been made of copper alloys containing more than 0.1% lead, this should be noted during delivery.

What is RoHS?

RoHS is Directive 2011/65/EU and associated amendments of the European Parliament and the Council dated 8 June 2011 on the restriction of use of certain hazardous substances in electrical and electronic equipment.

The RoHS Directive aims to minimise the release of hazardous substances into the environment. The directive serves as a guide for the respective regional regulations across Europe.

On 21 July 2021, the current exception 6c Annex III of the European RoHS Directive (Restriction of Hazardous Substances) officially came to an end.

An extension of this exemption for lead had already been requested from various market players in due time.

"The 21 July 2021 deadline has now passed. Existing exceptions only remain valid until the EU Commission has taken a decision on the application for renewal. "

If no extension is granted, a transitional period of 12-18 months shall apply from the date of publication of the rejection of the extension by the EU Commission. Accordingly, the maximum lead content of 0.1% in the material as defined in the REACH Regulation must not be exceeded in brass either.

Toxic Substances Control Act (TSCA)

The U.S. Environmental Protection Agency (EPA) has published a new rule under Section 6 of the Toxic Substances Control Act (TSCA) on 05.02.2021, according to which 5 PBT substances are to be banned in products in the USA in the short term, taking into account various exemptions.

The list of substances that will be banned for import, processing (manufacturing) as well as sale, but also in products mostly from 08.03.2021 in the USA, is as follows:

  • decabromodiphenyl ether (DecaBDE) (CAS No. 1163-19-5)
  • phenol, isopropylated phosphate (3:1) (PIP (3:1)) (CAS No. 68937-41-7), other names: Tris (4-isopropylphenyl) phosphate; CAS: 68937-41-7]
  • 2,4,6-Tris(tert-butyl)phenol (2,4,6-TTBP) (CAS No. 732-26-3)
  • hexachlorobutadiene (HCBD) (CAS No.87-68-3)
  • pentachlorothiophenol (PCTP) (CAS No.133-49-3)

According to the information available to us, 4 of the 5 substances are also part of the GADSL list and therefore already subject to declaration in the automotive supply sector.

Further information on the substances, areas of application and their US restrictions can be found at TÜV SÜD - USA: EPA bans five PBT chemicals and EPA: Assessing and Managing Chemicals under TSCA.

TÜV SÜD - USA: EPA bans five PBT chemicals

Due to the current situation and the pending U.S. ban, we are currently actively working to screen our products and materials for the presence of the designated substances. However, as this is a short-term legislative adjustment in the U.S., we cannot provide a definitive statement on this at this time.

As soon as reliable information is available, we will respond to your inquiry accordingly.

What challenges are there when manufacturing products with lead-free metals?

The addition of lead in copper alloys, including brass, ensures good chip breaking and light lubrication. This reduces friction and thus also heat generation during the manufacture of cable glands. The low material hardness of brass with added lead is another advantage that enables fast and easy processing.

The production of cable glands using lead-free materials and the procurement of raw materials therefore entailed complex process adaptations and higher costs. Currently, lead-free brass materials are often not available in the same coverage. The tensile behaviour when processing lead-free materials is different to that with the addition of lead in the material. This means that chip removal during production is a challenge, especially if both variants of the semi-finished products are used in production.

Additional work, which leads to overall higher costs and will inevitably have an impact on the prices of lead-free product variants, especially in the transitional period.

What are the differences between lead-free cable glands?

Lead-free cable glands are visually identical to those made of brass containing lead.

The product properties of cable glands with and without lead are also comparable. Both the internal LAPP laboratory and external testing institutes have confirmed that:

  • mechanical properties,
  • corrosion resistance and
  • EMC properties are comparable.

Both variants of the LAPP cable glands are also dust-tight in accordance with IP 68 and protected against continuous submersion up to a maximum of 10 bar and 100 metres of water depth for a maximum of 30 minutes.

Lead-free cable glands, just like those containing lead, are available to you from stock in metric sizes M12 to M63.


What application areas and environments are there?

Our lead-free cable glands are a good choice whenever the RoHS Directive and the REACH Regulation for lead are relevant for your machinery or systems.

Particularly if you manufacture or operate machines with long planning times or life cycles, it makes sense to rely on components that are lead-free and are decoupled from any currently applicable and future bans in the RoHS or REACH regulations.

Taking into account international sales markets or value chains and legislation, proactive sustainable action can also have a worthwhile impact on your planning.

How do you recognise lead-free cable glands from LAPP?

When selecting lead-free cable glands, look out for the designation “LF” in the article numbers of our products.

Products with this suffix are lead-free alternatives to the classic cable glands with otherwise the same product properties.

With our lead-free cable glands, you are therefore always on the safe side and can plan sustainably and for the long-term, even if the regulations are amended in future.
