Permabond launches PFAS-free thread sealant, LH055

A single-component anaerobic adhesive, LH055 cures in the absence of air between metal surfaces to form a durable seal with good chemical resistance. Suitable for use on a variety of metals including steel and brass, it is ideal for plumbing systems, cooling circuits, pumps, valves and other threaded metal pipe connections requiring dependable sealing and straightforward maintenance.

PFAS-free formulation

LH055's PFAS-free formulation makes it a thread sealing solution designed with the future in mind. As scrutiny of PFAS continues to grow, manufacturers are increasingly looking for products that can help them stay ahead of changing regulations and customer expectations.

For decades, PFAS-containing materials such as PTFE tapes have been widely used for thread sealing applications. However, many companies are now exploring PFAS-free alternatives as part of their long-term sustainability and compliance strategies. LH055 offers a simple way to make that transition without compromising on sealing performance.

The latest addition to Permabond's range of PFAS-free anaerobic adhesives, LH055 provides a high-performance thread sealing solution for manufacturers looking to reduce PFAS use throughout their operations and supply chains while preparing for the future.

Low breakaway torque for easy disassembly

Permabond LH055 has a relatively low breakaway torque (8 Nm/70 in.lb on zinc) which makes it ideal for future maintenance of parts, while still providing a strong, resistant seal. The product secures threaded fittings without causing them to seize. Should bonded parts need to later be disassembled, this can be done using normal tools. No excessive force or heat is required to undo the seal, leading to a greater product lifespan.

Permabond LH055 is suitable for sealing threaded pipes containing a variety of substances. It has KTW-BWGL as well as WRAS approval for contact with drinking water, as well as DVGW gas approval. In addition, the adhesive is highly chemically resistant, making it a well-rounded product suited to demanding industrial and plumping applications.
