PTFE Tape Bisan B870704 0.20 mm x 19 mm x 10 m – sealing tape

Bisan PTFE sealing tape B870704 is a thin, flexible thread sealant designed for creating reliable seals on threaded pipe joints, fittings and valves. The tape is 0.20 mm thick, 19 mm wide and 10 m long, made from polytetrafluoroethylene (PTFE) that provides low friction and chemical resistance. Its green colour aids identification for specific applications and it is suited for use where sealing against water, gas and hydraulic fluids is required.

Advantages

The PTFE construction ensures chemical inertness and temperature stability while offering low friction for easy thread engagement. The 0.20 mm thickness provides a compact wrap that fills thread gaps without adding excessive bulk. Being 19 mm wide, the tape covers typical pipe thread profiles efficiently and the 10 m length supplies enough material for multiple fittings. The product is contaminant-free, non-adhesive and resists degradation from common plumbing fluids.

Suitable for

• Sealing threaded connections on water supply pipes and fittings
• Gas line fittings where compatible with PTFE are required
• Hydraulic fittings and maintenance tasks in industrial equipment
• Plumbing and heating system installations and repairs

Key specifications

• Material: polytetrafluoroethylene (PTFE)
• Thickness: 0.20 mm
• Width: 19 mm
• Length: 10 m
• Colour: green
• Form: flexible non-adhesive tape for thread sealing

How to use

Clean and dry the male threads before application. Hold the tape on the end of the thread and wrap clockwise (in the direction of tightening) with slight tension, overlapping by approximately half the tape width on each pass to create 3–6 layers depending on thread pitch. Avoid covering the first thread to prevent tape extrusion into the system. Tighten the connection with appropriate tools to achieve a leak-free joint.

Usage recommendations

Use this PTFE tape for general plumbing, heating and compatible gas or hydraulic fittings; verify material compatibility with specific gases or fluids and follow local regulations for gas installations. Store in a dry place away from direct sunlight to maintain performance.
