Festo
159505
Pressure regulator LR-1/8-G
The Festo 159505 is a diaphragm regulator featuring a looped-through compressed air supply, a rotary knob with a lock, and a G1/8" prepared pressure gauge connection. Built with a brass housing and NBR seals, this component delivers a standard nominal flow rate of 600 l/min across a working pressure range of 1 to 20 bar and a pressure control range of 0.5 to 12 bar. It operates with a maximum pressure hysteresis of 0.2 bar, incorporates secondary exhaust and initial pressure compensation, and weighs 320 g with an assembly position that allows for any orientation.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
