It delivers an adjustable output in the 0–60 psi range and accepts inlet pressures up to 300 psi, making it suitable for lab and instrumentation applications that require stable, repeatable low‑pressure control. The unit uses 1\/8 in NPT connections, enabling straightforward inline installation in small‑diameter air lines and compatibility with Parker Watts fittings. Commonly encountered in microfluidic and microinjection workflows—such as PicoSpritzer systems—the R374‑01B provides fast, predictable response for pulsed or continuous low‑pressure delivery. As part of Parker’s miniature regulator line (R364\/R374), this model is offered alongside other port configurations and pressure ranges to suit a range of inline pneumatic needs in research and industry.\u003c\/p\u003e\u003c\/div\u003e","brand":"Schrader","offers":[{"title":"New","offer_id":46283579293930,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-020.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/parker-r374-01b-regulator","provider":"GTG Hardware","version":"1.0","type":"link"}
