The R374 is the aluminum bodied miniature regulator from the Parker Watts general line, the one that goes on a machine panel or at a workstation where a full size regulator would be three times the part for no extra benefit.\u003c\/p\u003e\n\u003ch3\u003ePublished specification\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePort size: 1\/4 in.

R374 is aluminum, R364 is brass. Choose the brass body where the ambient is corrosive or where a specification calls for it; otherwise the aluminum is lighter and cheaper and does the same job.\u003c\/p\u003e\n\u003ch3\u003eRelieving, and why it matters\u003c\/h3\u003e\n\u003cp\u003eThis build is relieving, which means that if you dial the setting down while the downstream line is already pressurised, the excess bleeds out through the bonnet instead of staying trapped. That is what you want on a line feeding a cylinder or a clamp. If you are regulating into a closed vessel, or into anything where a small continuous bleed is unacceptable, specify the K option for non relieving instead.\u003c\/p\u003e\n\u003ch3\u003eFitting\u003c\/h3\u003e\n\u003cp\u003eNo gauge is supplied. Two 1\/8 in. gauge ports are provided, one on each side, so the gauge can face whichever way the panel needs. Bracket kit SA161X57 includes the panel mount nut; the panel hole is 1.250 in. Install with the flow arrow pointing downstream and leave clearance for the knob.\u003c\/p\u003e\n\u003cp\u003eParker Watts R374-02C miniature relieving air pressure regulator, 1\/4 in.
