Festo
173649
Pressure regulator LR-1/4-D-O-MINI-NPT
The Festo 173649 is a mini industrial component from the D-series featuring 1/4 NPT pneumatic connections for both ports 1 and 2. It operates within a pressure range of 0.1 MPa to 1.6 MPa (1 bar to 16 bar) and provides a pressure regulation range of 0.5 bar to 12 bar with a maximum pressure hysteresis of 0.02 MPa (0.2 bar / 2.9 psi). The unit processes compressed air conforming to ISO 8573-1:2010 [7:4:4] or inert gases, permits oil lubrication operation, and complies with RoHS material standards while maintaining a CRC 2 moderate corrosion stress rating.

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.
