STAUFF Screw-to-connect coupling with poppet valve male tip QRC-HSN-19-M-G12-B-W3
- ERIKS:1032653
Screw-to-connect couplings of the HSN Series consist of a female body with external thread and a male tip with a screw sleeve. The Series is developed for particularly heavy-duty applications for connecting hydraulic lines up to DN38 (1-1/2").
Coupling (screwing) and uncoupling (unscrewing) of the two halves is safe and very easy. The coupling is designed to open both valves when connected together and due to their rugged design, higher operating and burst pressures, they are well suited for heavy-duty service conditions in construction machinery.
The Series was developed according to ISO 14541 (BG 1-6) in the following nominal sizes 06, 10, 12, 16, 19, 25, 38 (1/4" - 1-1/2").
