Question by: Harold J on May 14, 2025, 10:31 AM
got a HK series socket already, is this the right plug half for it or am i mixing standards
Answer by: Customer Support on May 15, 2025, 8:05 PM
The key detail is interchange. This plug half is an HK Series in brass and it is ISO 7241-1 Series B interchange, with a ball lock internal connection. Pairing it with a coupler body that is also ISO 7241-1 B is the match you want.

It’s an HK Series male plug half that follows ISO 7241-1 Series B interchange. It uses a ball lock internal connection and has a 2 way valve.

what's the lowest temperature this coupling can handle? got equipment that sees some pretty brutal winters and need to know if brass is gonna hold up
Answer by: Customer Support on May 30, 2025, 6:09 AM
Rated down to -40 degrees, so cold weather use are well within range for this one. The brass construction and Buna-N seals are both compatible with that lower limit, which makes it a solid pick for outdoor hydraulic setups that take a beating in winter conditions.
