Bsc Preferred T966SF4PK Self-fusing Putty Tape 600V 4 Pack

Product Description

The BSC PREFERRED T966SF4PK is an electrical-grade, rubber-based self-fusing putty tape designed for fast insulation buildup on irregular and non-flat surfaces. Made from non-corrosive synthetic rubber, it wraps, stretches, and molds around fittings, valves, and other complex geometries without requiring adhesive - the material fuses to itself on contact. Rated for connections up to 600 volts, it operates across a temperature range of 32 degrees F to 176 degrees F. Each case contains 4 rolls. Electricians and plumbers reach for this tape when standard flat tape cannot conform cleanly to the surface geometry of a termination or fitting.

This tape is suited for electrical and mechanical insulation applications where the work surface is curved, threaded, or otherwise non-planar. Common applications include insulating wire splices, terminal connections, valve bodies, and pipe fittings in residential and commercial settings. The peel-off liner keeps the tape clean and ready for use until the moment of application, making it practical for field work. The self-fusing construction eliminates the need for additional securing materials once wrapped.

Compatibility

Designed for use on non-flat surfaces including pipe fittings, valves, wire splices, and terminal connections in electrical and plumbing applications up to 600 volts.

Installation Notes

Installation is typically performed by licensed electricians or plumbers depending on the application. De-energize all circuits and confirm zero voltage with a meter before applying tape to any electrical connection, following NEC guidelines. Clean and dry the surface before wrapping to ensure proper self-fusion. Stretch the tape moderately while wrapping to activate the self-bonding properties and achieve a smooth, void-free buildup.
