Chemtrol 6529 Schedule 80 pipe nipple

This Chemtrol 6529 pipe nipple is a 3-inch Schedule 80 fitting with 3/4-inch male NPT threads on both ends. It is designed for chemical-process piping that handles acids, bases and solvents in industrial or laboratory systems.

Verify thread size pressure and temperature limits

Confirm that the existing piping uses 3/4-inch NPT threads and Schedule 80 dimensions before ordering. The fitting is rated for a maximum operating pressure of 360 psi and a temperature range of -20 to 280 degrees Fahrenheit, so the system must stay within those limits.

Kynar PVDF body resists corrosion in harsh media

The red polyvinylidene fluoride body provides broad chemical resistance, allowing the nipple to join compatible valves, filters or instruments without adding metallic corrosion risk. Its male-to-male threaded ends connect directly to female NPT ports, keeping the flow path free of additional adapters.

What comes in the box with the Chemtrol 6529 pipe nipple?

The box contains the single 3/4" x 3" Schedule 80 MNPT pipe nipple made from Chemtrol polyvinylidene. No gaskets, sealant or additional fittings are included.

Which Chemtrol 6529 size should I choose for a 3/4-inch Schedule 80 system?

The 360 psi maximum operating pressure applies at temperatures up to 280 °F; above that temperature the allowable pressure drops, and the minimum service temperature is -20 °F.
