3/4" Red Brass Pipe Nipple

This 3/4 inch nominal pipe size nipple is made from red brass and features male NPT threads on both ends. It is manufactured to Schedule 40 wall thickness and conforms to ANSI B 1.20.1 and ASTM B687 standards. The fitting suits plumbing installations requiring a 7 inch overall length.

Upgrade From Standard Brass Or Steel

Red brass construction provides a higher copper content than standard yellow brass or plain steel nipples. The material choice is worth it when the system demands better resistance to dezincification and seasonal condensation. The Schedule 40 rating supports pressures up to 953 PSI at temperatures between -20 and 300 degrees Fahrenheit.

Threaded Installation Considerations

The MNPT threads on both ends allow direct connection to female NPT fittings without additional adapters. Apply a suitable pipe thread sealant to ensure a leak-free joint at the rated pressure. Over-tightening can damage the red brass threads, so stop when the joint feels secure and the sealant has engaged.

Questions about this item

What size female NPT fitting does the 3/4 inch MNPT thread connect to?

The nipple has 3/4 inch male NPT threads on both ends, matching standard 3/4 inch female NPT fittings.

How do I seal the MNPT threads correctly without cracking the brass?

Apply PTFE tape or pipe thread sealant to the male threads, then hand-tighten plus one to two turns with a wrench; over-tightening can split the red brass.

When should I plan to replace this Schedule 40 red brass nipple?

Inspect periodically for dezincification, erosion or thread damage; replace if leaks appear or the material shows pinkish discoloration from zinc loss.
