Thread Sealant Cord Bisan LOCKER 30 m — thread sealing cord for pipe and screw threads

Bisan LOCKER thread sealant cord, 30 m roll, is a ready-to-use sealing thread designed to fill gaps in pipe and screw threads and to prevent leaks of water, gas or other liquids in plumbing and HVAC installations. The cord is compatible with metal and plastic fittings and creates a compact, conforming seal that is useful for both new assemblies and repairs. This thread sealing cord is supplied on a convenient roll that allows controlled dispensing and reduces waste during application.

Advantages

The sealing cord provides a uniform seal that adapts to irregularities in threaded connections, reducing the need for additional sealants or tapes. Its ready-to-use format requires no mixing or curing, enabling immediate assembly after application. Compatible with a variety of pipe materials, the cord offers chemical resistance suitable for common plumbing and heating media and maintains sealing performance under pressure and temperature variations typical for domestic and light commercial systems.

Suitable for

• Sealing threaded pipe joints in plumbing systems
• Repairing leaks in screw fittings on water and heating installations
• Sealing connections in HVAC equipment and radiators
• Use with metal and plastic fittings where a conforming seal is required

Key specifications

• Form: flexible sealing cord on a roll
• Length: 30 m per roll
• Compatibility: suitable for metal and plastic threaded connections
• Function: fills thread gaps to prevent leakage of water, gas or other liquids
• Application temperature range: suitable for typical plumbing and HVAC operating conditions

How to use

Clean and dry the threaded surfaces before application to ensure optimal adhesion and sealing. Cut the required length of cord from the roll, wrap it tightly around the male thread in the direction of threading to avoid unravelling, and ensure the cord sits evenly across the thread profile. Assemble the joint immediately after applying the cord, tightening to the appropriate torque for the fitting material. Excess cord extending beyond the connection can be trimmed or compressed into the joint.

Usage recommendations

For reliable sealing, use the cord on clean threads and avoid oil-contaminated surfaces. Do not stretch the cord excessively during application, and select an appropriate wrap thickness according to the thread pitch and fitting material. Verify compatibility with media and temperature ranges in your specific installation before prolonged exposure to aggressive chemicals or unusually high temperatures.
