Couplings
Threaded Fittings
Riegler couplings join two female ports and often act as reducing connectors between different thread sizes. Versions with an external hexagon ease tightening.
The range covers more than 170 items in brass, nickel-plated brass and stainless steel 1.4571. Threads run from M5 and G 1/8 up to G 1, many in a reducing design.
