SS 1/8" F-PIPE X 1/8" F-PIPE COUPLING

Description & Features

Rated to 6,000 PSI maximum dynamic pressure, the SS 1/8" F-PIPE X 1/8" F-PIPE Coupling is a straight stainless steel union fitting designed for inline connections between two female-threaded lines. Both ends feature 1/8"-27 Female NPTF threads conforming to SAE J476, providing a dry-seal mechanical connection that resists leakage under pressure without relying solely on thread sealant.

Constructed from stainless steel, this Brennan Series 5000 coupling suits applications where corrosion resistance is a priority. The compact straight configuration makes it well suited for tight installations where a direct, low-profile union between two female pipe ends is required.

Question by: Freddie M on Jan 13, 2026, 6:46 PM
So this is just a straight-up connector for two female pipe ends, right? No check valve or anything fancy built in?
Answer by: Customer Support on Jan 15, 2026, 3:20 PM
Correct, it's a simple straight coupling. Its purpose is to join two female-threaded 1/8" NPTF pipes directly in line.
