  • Resists acids, bases and solvents with Chemtrol Kynar PVDF material
  • Handles up to 360 psi working pressure in Schedule 80 systems
  • Operates from -20 to 280 °F for broad temperature range
  • 1 inch NPT male threads on both ends for secure connections
  • 4 inch overall length suits compact piping installations

Chemical-resistant Schedule 80 nipple

The Chemtrol 6529 nipple is a 1-inch nominal Schedule 80 pipe nipple built from Kynar polyvinylidene fluoride. It handles acids, bases and solvents in industrial piping systems where metal fittings would corrode. The red body identifies the material at a glance.

Male NPT threads on both ends

Each end carries a 1-inch male NPT thread so the nipple joins two female-threaded Schedule 80 components without adapters. The 4-inch overall length provides a fixed spacing between the connected fittings. Thread sealant compatible with Kynar ensures leak-free joints.

360 psi at 280 °F pressure rating

The nipple withstands 360 psi maximum operating pressure at temperatures up to 280 °F and remains functional down to -20 °F. Systems that exceed either limit need a different fitting. Buyers who need higher pressure or temperature ratings cannot use this part.

Questions about this item

Will the Kynar material need replacement after exposure to 280 °F temperatures?

The nipple is rated for continuous service up to 280 °F; above that limit the PVDF can degrade and should be inspected for replacement.

What pressure limit is reached first during sustained operation at 360 psi?

The maximum operating pressure is 360 psi; sustained use at that rating is the design ceiling before a safety factor would require derating.

Does the Schedule 80 wall generate noticeable heat or noise when fluid runs all day?

As a static Schedule 80 PVDF nipple it adds no mechanical noise or heat; only the pumped fluid temperature affects the assembly.
