Chemtrol 6529 Kynar Pipe Nipple 3/4" MNPT x 5" Sch 80

3/4" Kynar Schedule 80 Nipple

This Chemtrol 6529 pipe nipple is a 3/4-inch male NPT fitting constructed from polyvinylidene fluoride, known by the trade name Kynar. It is designed for plumbing systems handling acids, bases, and solvents where high chemical resistance is required. The Schedule 80 wall thickness provides a maximum operating pressure of 360 psi for demanding fluid transfer applications.

For Corrosive Chemical Lines

This fitting suits installers building or repairing Schedule 80 piping systems that carry aggressive media at temperatures between -20 and 280 degrees Fahrenheit. The red colour coding identifies the Kynar material for easy visual verification. It is not intended for systems requiring welded joints, flanged connections, or materials rated for pressures exceeding the 360 psi limit.

Five-Inch Threaded Connection

The nipple measures five inches overall with male NPT threads on both ends, allowing a direct threaded connection between two female Schedule 80 fittings or valves. It comfortably handles the full 360 psi rating within the stated temperature range. Headroom diminishes if the system design requires a different thread standard, a longer spool piece, or a material compatible with media outside the specified acid, base, and solvent resistance.
