Compressed Air and Pneumatic Couplings
Robust Couplings (High-Performance Couplings)
Riegler robust couplings are high-performance couplings for demanding compressed air applications with larger nominal widths such as NW 7.2 to NW 7.8. Grommets and nipples are made of hardened and galvanized steel, in part with PTFE sealing on the threads.
The range of more than 160 items offers ports as male and female threads in R and G 1/8 to 1/2 as well as grommets in clear widths LW 6 to LW 13. The rugged construction is designed for high throughput and mechanical stress.
