Mjic-Mbspp Elastomeric Sealed

Description & Features

A straight steel adapter connecting a 1/2" Male JIC fitting (3/4-16 UNF thread) on one end to a 1/4" Male BSPP fitting (G 1/4-19 thread) on the other, the Mjic-Mbspp Elastomeric Sealed is designed for hydraulic lines where JIC and BSPP thread standards need to be joined in a single inline connection. The elastomeric seal on the BSPP end provides a reliable, leak-resistant interface suited to hydraulic circuits where a reliable face or port seal is required.

Manufactured by Adaptall, this adapter measures 38.6mm in length with a 19mm wrench width, making it compact enough for installations where space is limited. Steel construction supports the mechanical demands typical of hydraulic systems running these thread combinations.

Got a piece of equipment running a JIC line that needs to tie into a BSPP port, this the right adapter to bridge that gap?

That's what this one's built for. One end is 1/2" Male JIC on a 3/4-16 UNF thread, and the other is 1/4" Male BSPP on a G 1/4-19 thread. The elastomeric seal on the BSPP end handles the face or port seal so you get a leak-resistant connection without needing extra fittings in between. Steel construction, straight profile, and it comes in at just under 39mm long, so it'll fit in tighter spots without much fuss.

You'll need a 19mm wrench for tightening this adapter.
