Ask A Question

Description & Features

Designed for general pneumatics, industrial plant environments, and fluid transfer applications, the 500 Series Brass Coupling, Female Half from Hansen and Gromelle provides reliable push-to-connect functionality with a 3/8" NPTF port on the secondary end. The ball lock internal connection type and sleeve lock safety mechanism work together to maintain a secure hold under operating conditions, reducing the risk of accidental disconnection.

Constructed from brass with a Buna-N seal, this female half coupling is well-suited for a range of pneumatic media at temperatures down to -40°F. The one-way valve configuration controls flow direction, while the 3/8" end sizing on both connections ensures compatibility with standard pneumatic lines. Its compact 1.19" width makes it practical for installations where space is a consideration.

Question by: Terry C on Dec 3, 2025, 2:59 PM
So this thing is brass, right? How cold can it get before I have to worry about it cracking or somethin'?
Answer by: Customer Support on Dec 5, 2025, 9:07 AM
This female half coupling is rated down to -40°F, thanks to its brass construction and Buna-N seal, so you shouldn't have any issues with cracking in normal cold-weather conditions.
