Question by: Diane T on May 26, 2025, 7:00 AM
got a 1" BSPP female port on a manifold block and need to step down to 3/4" BSPP male for a fitting downstream, this bushing do that?
Answer by: Customer Support on May 27, 2025, 10:17 AM
Yeah, that's exactly what this one handles. The female end is 1" BSPP (G 1-11) and the male end is 3/4" BSPP (G 3/4-14), so it threads into your 1" port and gives you a 3/4" male connection on the other side. Steel construction, 56mm overall length, and a 41mm wrench flat so you can get a good grip on it during install.

Will this bushing work to adapt a 3/4" BSPP male fitting to a 1" BSPP female fitting?
Answer by: Customer Support on Jul 5, 2025, 12:43 PM
Yes, that's exactly what it's for. This extended bushing has a 3/4" BSPP male end and a 1" BSPP female end, so you can easily connect those two different sized fittings.

got a port that’s G 1 (1 inch BSPP) female, will this bushing step it down to G 3/4 male on the other side?
Answer by: Customer Support on Feb 19, 2026, 1:21 PM
Function-wise, it is a straight extended bushing that adapts between a female G 1 (1 inch BSPP, G 1 - 11) connection on side 2 and a male G 3/4 BSPP (G 3/4 - 14) connection on side 1.
