Question by: Rhonda W on May 14, 2025, 5:20 PM
got two female bspP ports that are both g 1/4, is this the straight coupler to join em together?
Answer by: Customer Support on May 16, 2025, 4:11 PM
For tying two ports together, it gives you female BSPP on both ends with the same callout, G 1/4 - 19, and both sides are 1/4 inch.
Question by: Patty R on Feb 11, 2026, 7:01 PM
Both ends on this thing are female BSPP, right? Just want to make sure before I order it for a G 1/4 line connection.
Answer by: Customer Support on Feb 12, 2026, 7:53 PM
Correct on both counts. Both ends are female BSPP with a G 1/4 - 19 thread callout and a 1/4" size, so you've got matching female connections on each side. It's a straight coupling, no offsets or reducers, just a clean inline female-to-female BSPP setup in steel.

So, this here is just a straight coupling, right? Both ends are the same?
Answer by: Customer Support on Aug 20, 2025, 6:09 AM
Correct, this is a straight coupling. Both sides feature female BSPP connections with a G 1/4 - 19 callout and a 1/4" size.
