FD42 Series, Pioneer 4000 Interchange Quick Disconnect, Male Half, -04 Coupling, 1/4-18 Female NPT

It is a Pioneer 4000 interchange style male half. It is listed as interchanging with Pioneer 4000-2 and Safeway S20-A, and this one has a 1/4-18 female NPT thread with a -04 coupling size.

Yes sir, this FD42 series male half interchange quick disconnect is made to work as a replacement for the Pioneer 4000-2. It also swaps with the Safeway S20-A.

it's a direct interchange for both Pioneer 4000-2 and Safeway S20-A, so you won't need a different fitting. The push-pull ball latch design on these FD42 units connects and disconnects the same way you'd expect from those Pioneer couplings, and the self-sealing poppet valve keeps things tight on both ends whether you're under high or low pressure. Body is zinc plated steel with zinc poppet guides, and the standard seal is Buna-N, so just make sure that seal material works with whatever fluid you're running.
