Parker GP307 VALVE, 3/8 inch, brass, STEAM OR WATER service

Anderson-Bolds stocks and sells GP307 direct. We have been an authorized Parker distributor out of Beachwood (Cleveland), Ohio since 1933, so the part comes through the manufacturer's own channel with warranty and factory support intact — not from a broker. Order online or call (216) 360-9800.

GP307 is quoted rather than list-priced, which is normal for configured and engineered Parker items. Add it to a Request for Quote and Anderson-Bolds will come back with current price and lead time, usually within one business day.

Anderson-Bolds confirms the on-hand quantity and ship date for GP307 when the order is received — the online catalog does not publish a live shelf count, so nothing here is a promise the warehouse has not checked. Stocked items ship the same business day; anything that has to come in is quoted with a lead time before you are charged.

Tell us the duty rather than the part number. Anderson-Bolds' application engineers size valves for a specific job — voltage, medium, temperature, flow, enclosure rating — and will cross-reference GP307 to the right Parker configuration or to another line we carry. Send it through the Request for Quote form and you will get a person, usually within one business day.
