Produced in food grade chrome plated brass, these 1/8" flow size couplings are more durable and withstand higher pressures. They are available with internal shut-off valves or straight through. All 20CB couplings interconnect with all other 20AC and 20PP couplings as well as other similar industry thumb-latch type couplings. Typical lead time is 8-10 weeks but varies based on demand.
