Sealing kit Bisan B870799 — sealing paste and hemp pack, sachet 28 g

Bisan B870799 sealing kit is supplied as a compact 28 g sachet containing sealing paste and hemp pack. The kit is intended for creating or repairing threaded pipe joints and fittings, offering a pliable sealing material that fills gaps and improves leak tightness. Its small format makes it suitable for maintenance, small repairs and on-site assembly where a ready-to-use combination of sealing paste and hemp is required.

Advantages

The combined sealing paste and hemp provide a flexible, conforming seal that adapts to irregular thread profiles and minor surface imperfections. The paste ensures good adhesion between hemp fibres and metal surfaces, while the hemp adds body to seal larger clearances. Supplied in a premeasured sachet, the kit is convenient for single repairs and avoids excess waste. The materials are formulated for use with water and heating installations and permit straightforward application without specialized tools.

Suitable for

• Sealing threaded pipe joints in water supply systems
• Repairing minor leaks in heating installations
• Assembling fittings where a compact, ready-to-use seal is needed
• On-site maintenance and emergency repairs

How to use

Clean the threads and mating surfaces to remove dirt, grease and old sealant residues. Take the required amount of hemp and wrap it uniformly around the male thread in the direction of tightening, leaving the thread profile visible where specified by the fitting type. Apply a thin, even layer of the sealing paste over the hemp or directly onto the threads to ensure adhesion and fill remaining gaps. Assemble and tighten the joint according to the fitting manufacturer’s torque recommendations. After installation, check for leaks and re-tighten if necessary following a short test under working pressure.

Usage recommendations

Use the sachet contents on a single repair or assembly to ensure consistent performance. Store unopened sachets in a cool, dry place away from direct sunlight. When working on potable water systems, follow local regulations and, where required, flush the system after repair. Wear gloves to avoid direct contact with paste components and clean tools and hands after application.
