Brass construction and dual NPTF thread compatibility make this a reliable choice for bulkhead installations requiring a reduction between two different pipe thread sizes. The Danfoss / Eaton Weatherhead 1341 Bulkhead Coupling connects a male 1/2-14 NPTF thread to a female 1/4-18 NPTF thread, allowing it to serve as a through-panel or through-wall fitting in compressed air and fluid transfer systems.
Manufactured by Eaton Aeroquip, this straight adapter benefits from Dura-Kote plating, which provides corrosion resistance suited to demanding industrial environments. The fitting is rated for operating pressures above SAE standards, reflecting Aeroquip's higher-pressure design criteria across its adapter line. With a package weight of 0.5 lb and a hex size of 0.938 in., the fitting is straightforward to install with standard tooling.

Question by: Diane A on Sep 29, 2025, 10:10 AM
Will this fitting hold up if I'm running air tools pretty much all day?

This Eaton Weatherhead coupling is made from brass, which provides good durability for continuous use applications. It's designed for higher operating pressures that exceed SAE standards.
Question by: Rex C on Aug 21, 2025, 11:03 AM
bulkhead coupling got a 1/2-14 NPTF on one end and 1/4-18 NPTF on the other -- is that right for this part?
Answer by: Customer Support on Aug 23, 2025, 7:04 AM
That's what you've got with the 1341. Male 1/2-14 NPTF threads on one end, female 1/4-18 NPTF on the other, brass construction throughout. It's built as a bulkhead-style coupling, so it's meant to pass through a panel or wall and lock connections on both sides. Just make sure your mating fittings match those thread specs before you button everything up.
