HK Series Industrial Interchange Series B Brass Hydraulic Quick Disconnect, Male Half, -02 Coupling, 1/8-27 Female NPT

This male half uses 1/8-27 female NPTF threads, and it is a -02 coupling size. If your connection point is truly a 1/8-27 female NPT port, you would need a male NPT thread on the coupling, not a female NPTF.

Its brass construction and stainless steel springs offer good corrosion resistance and fluid compatibility. The standard seal is Buna-N, but you can get it with PTFE, Neoprene, FKM, EPDM, and Kalrez seals for different fluids.

Buna-N is the standard seal, and it handles a temperature range of -40°F up to 250°F. For most hydraulic oil applications that fall within that range, it holds up well under regular use. If your fluid or operating temps push outside that window, there are other seal options available including Neoprene, EPDM, FKM, PTFE, and Kalrez, each rated for different temperature ranges depending on what you're running.

For interchange, it follows ISO 7241-1 Series B dimensions, so it matches the common “Series B” style used across a lot of industrial couplers. It is a -02 size male half with 1/8-27 female NPTF threads on the pipe end, and the other side is push-to-connect.
