Application Suitability
This Chemtrol pipe nipple handles acids, bases and solvents in Schedule 80 systems. The Kynar polyvinylidene construction resists aggressive chemicals at temperatures from -20 to 280 degrees F. It suits industrial process lines that demand high chemical resistance.
Connection Verification
Confirm your piping uses 3/4 inch NPT male threads on both ends before ordering. The nipple is built to Schedule 80 dimensions and carries a 360 psi maximum operating pressure rating. Ensure the surrounding pipework matches this schedule and pressure class.
Thermal And Pressure Limits
Normal service stays within the -20 to 280 degree F range while pressure remains at or below 360 psi. The red Kynar body maintains structural integrity across this window without degradation. No moving parts or seals are present, so noise and vibration are not factors.

Questions about this item
What comes in the box and do I need to buy thread sealant separately?
The box contains one Chemtrol 6529 nipple with 3/4" male NPT threads on both ends. Thread sealant or tape is not included and must be purchased separately for installation.
The listing shows Schedule 80 — is that the only wall-thickness option for this size?
Yes, this nipple is manufactured to Schedule 80 dimensions for 3/4" nominal pipe size, providing the heavier wall required for 1,360 psi pressure rating.
What does the 1,360 psi rating mean when the nipple is installed in a hot chemical line?
The 1,360 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.
