Chemtrol 1/2" Kynar Schedule 80 Nipple
This Chemtrol 6529 pipe nipple is a 1/2-inch nominal size fitting made from polyvinylidene fluoride, sold under the Kynar trade name. It features male NPT threads on both ends in a close TBE configuration with an overall length of 1 1/8 inches. The Schedule 80 wall suits industrial piping systems handling acids, bases and solvents. The red colour identifies the material in the field.
Suits chemical-process lines to 360 psi
Installers needing a corrosion-resistant nipple for aggressive fluids at up to 360 psi and 280 Degrees F will find this part appropriate. The -20 Degrees F minimum temperature allows use in chilled-service lines. It is not for systems requiring female threads, flange connections or a longer lay length than the close TBE design provides. Buyers needing different nominal sizes or pressure classes must select another fitting.
360 psi maximum operating pressure at 280 Degrees F
The single specification that decides fit is the 360 psi pressure rating at the 280 Degrees F upper temperature limit. Verify that the system design pressure and temperature stay within these limits before specifying this nipple. The 1/2-inch NPT threads and Schedule 80 dimension must also match the mating components.

Questions about this item
What thread size and type does the Chemtrol 6529 nipple use for mounting?
Both ends have 1/2 inch male NPT threads, giving a close, threaded connection on each side.
What is the correct way to seal the 1/2" MNPT threads on this Kynar nipple?
Apply PTFE tape or compatible pipe dope to the male threads, then tighten to the recommended torque for Schedule 80 plastic fittings; over-tightening cracks the material.
At what temperature should I plan to replace this Schedule 80 Kynar nipple?
The nipple is rated from -20 °F to 280 °F; sustained exposure near the upper limit will degrade the polyvinylidene fluoride and require replacement.
