Refinery Supply

What Refinery Supply does

Refinery Supply Co. is a U.S.-based manufacturer of precision pressure measurement and petroleum testing instruments founded in 1924 and headquartered at 604 South 10th Street, Broken Arrow, Oklahoma. The company produces deadweight gauges (up to 20,000 psi), portable hydraulic deadweight testers, electrically heated centrifuges, LPG testing apparatus, sampling equipment, and temperature and gauging instruments for oil and gas industry customers including refineries, exploration and production operators, natural gas pipeline companies, LPG distributors, and petroleum testing laboratories. All products are hand-made in the USA, conform to ASTM and API testing standards (ASTM D4007, D4057, D1657, D2713-15, D1837, D2158, ASTM 59F, API 10.4), and are backed by NIST-traceable calibration certifications at ±0.02% accuracy.

The company operates a sales-assisted e-commerce model, with customers browsing the product catalog at refinerysupply.com and placing orders by phone. Pricing ranges from roughly $200 for accessories and certifications to over $10,000 for high-pressure deadweight testers. Revenue is generated across four streams: capital equipment sales (gauges, testers, centrifuges), replacement parts (consumables such as gaskets, valves, and orifice plates), repair services, and NIST calibration services. Refinery Supply also maintains a registered Kolor Kut brand for water-finding paste used in fuel testing.

Effective July 1, 2026, Robinson Manufacturing Co., Inc. — a family-owned manufacturer of oil centrifuges and petroleum products in business since 1954 — announced its acquisition of Refinery Supply Co. Under the new ownership, manufacturing processes are intended to remain unchanged, but customer service contacts have transitioned to the Robinson team, with Rico A. Tejeda identified as President of the acquirer. The acquisition combines Refinery Supply's deadweight gauge expertise with Robinson's centrifuge capabilities, indicating a consolidation play in the niche petroleum testing instrumentation segment.
