Swagelok KPR1DJC412A20000 Pressure Regulators

Swagelok's KPR1DJC412A20000 is a stainless-steel, single-stage pressure regulator designed to convert high upstream pressures to a precise 0–25 psig downstream pressure; it's part of the KPR family and uses 1/4 in. FNPT ports. The unit features a 316 stainless steel body and a PCTFE seat, with a nominal Cv of 0.06 and an inlet rating up to 3600 psig (248 bar), enabling use in high-pressure gas systems while delivering controlled, low-pressure output. Swagelok describes these regulators as capable of minimizing downstream pressure droop and maintaining a constant setpoint under varying flow demands, which is essential for instrumentation and processes that require stable gas supply. Within the KPR series, several configuration codes exist (including A, B, F, and J variants) that share 1/4 in FNPT connections and the same 0–25 psig control range, allowing you to choose a version that matches mounting, seating, and installation preferences.
