Male Pipe to Valco External Adapters

male pipe to external adapter

Male pipe adapters make a minimum volume connection from the female pipe fittings typically found on pressure gauges and regulators to Valco external fittings. Standard material is 300 series stainless.

Note: We do not manufacture adapters with 1/16" external fittings because they have very thin, easily distorted walls. We recommend use of male pipe to Valco internal adapters (PZAs).

Male pipe-to-external adapters are non-stock items, available by special order. Contact us for more information.

Pipe thread sizes

NPT, National Pipe Thread, is a standard developed a long time ago by people without rulers. 1/8" NPT is nowhere close to 1/8"! Measure the diameter of the fitting across the narrow end. You can also count the number of threads in a 1" section. Then look at the illustration below to determine the correct size needed.

TECH TIP

Because of their dead volume and the risk of thread leaks, pipe fittings are a poor choice for trrace gas analysis. Thread sealants, particularly PTFE tape, cannot boost their performance to adequate levels. For trace gas applications, choose Valco zero dead volume fittings with gold-plated stainless ferrules.
