Product Description

Hank of Hemp is a traditional sealing material made from natural plant fibres, commonly used by installers to create leak-proof connections on threaded pipe joints. The fibres are wrapped around the male thread and used in conjunction with a jointing compound such as Boss White or Boss Green, forming a tight and durable seal once the joint is tightened.

 
The hemp works by filling the small gaps and imperfections within the thread, helping to prevent water leakage and maintain system pressure . When combined with a sealing paste, it also allows the threads to tighten smoothly while locking the fibres in place for long-term performance.

 
This method is widely used across plumbing, heating and mechanical systems, particularly on metal pipework where a strong, reliable seal is essential. It remains a popular choice due to its effectiveness in applications where other sealing methods may struggle, especially on older or less precise threaded fittings.

Applications

Ideal for use on threaded pipe joints in plumbing, heating and mechanical systems, including applications such as water systems, heating installations and general pipework where a dependable, watertight seal is required.
