Thread Sealant Paste Bisan GB1 250 g tube — for water and gas pipe threads

Bisan GB1 thread sealant paste in a 250 g tube is formulated for sealing metal threaded pipe connections in water and gas installations. The paste is supplied in a squeezable tube that allows controlled application to male or female threads, forming a durable, leak-resistant joint after assembly. It is intended for use where a reliable mechanical seal is needed on metal fittings and valves in plumbing, heating and gas systems.

Advantages

The paste provides reliable sealing of threaded pipe connections for water and gas, resisting washout and maintaining sealing properties under typical operating conditions. The tube format enables precise application and reduces waste during assembly. The product is compatible with standard metal threads and creates a joint that remains serviceable while allowing later disassembly if required.

Suitable for

• Sealing threaded metal pipes and fittings in domestic and commercial water systems
• Pipe joints and fittings in heating installations and radiators
• Gas pipe thread sealing where approved materials are required
• Maintenance and installation work on valves, meters and pumps with metal threads

Key specifications

• Form: paste in squeezable tube (250 g)
• Application: metal threaded connections for water and gas systems
• Compatibility: intended for use on standard metal threads
• Performance: creates a leak-resistant, removable seal suitable for plumbing and heating
• Packaging: tube for controlled dispensing and reduced product loss

How to use

Ensure threads are clean, dry and free of oil, dirt or old sealant. Cut the tube tip and apply an even layer of paste to the male threads or to both mating surfaces as appropriate. Assemble the connection and tighten to the required torque for the fitting. Excess paste should be wiped away after assembly. Allow the joint to settle before applying system pressure, following any system-specific curing or handling times for safe operation.

Usage recommendations

Use the product according to local regulations and equipment manufacturer instructions when working on gas systems. For best results, store the tube in a cool, dry place and avoid contamination of the paste during application. If in doubt about compatibility with a specific material or system, perform a small test joint or consult technical documentation.
