Chemtrol 6529 Schedule 80 Pipe Nipple

This Chemtrol 6529 pipe nipple is a Schedule 80 fitting built for chemical process lines. It connects two female NPT ports in systems handling acids, bases or solvents. The polyvinylidene fluoride body, sold under the Chemtrol trade name, resists corrosion across a wide temperature range.

Suited for corrosive fluid systems.

Installers running aggressive chemicals at up to 360 psi and 280 °F will find the material and pressure class appropriate. The red colour coding identifies the Chemtrol line at a glance. Plumbers needing only potable-water service or lower pressure ratings should look at alternative materials.

1/2-inch NPT male threads on both ends

Each end carries a 1/2-inch male NPT thread, giving a 3-inch overall length between engagement faces. This dimension fixes the centre-to-centre spacing when joining two female fittings, so verify the required gap before ordering.

Questions about this item

What thread size and type does the 1/2" Schedule 80 nipple use on both ends?

Both ends are 1/2" male NPT threads, matching standard Schedule 80 fittings.

How do I seal the male NPT threads correctly during installation?

Apply PTFE tape or pipe dope on the male threads only, then tighten to the recommended turns past finger-tight to avoid cracking the Kynar body.

When should I replace this nipple in chemical service?

Inspect regularly; replace if threads show wear, the red Kynar body discolours, or the system exceeds the 280 °F or 360 psi limits.
