What Tompkins Industries makes

Tompkins Industries is an ISO 9001 certified manufacturer and master distributor of hydraulic adapters, fluid power products, and accessories. The core catalog runs to more than 8,000 configurations of hydraulic adapters and tube fittings in steel, stainless steel, and brass, in both SAE and metric sizes, rated for working pressures to 10,000 psi. Around that core sit flanges and flange adapters, O-ring face seal adapters from 1/16 inch to 3 inch, live swivels, ball valves in full-size and mini versions, drain and needle valves, and quick-disconnect couplings.

The company also carries a line of maintenance and diagnostic products that go beyond raw fittings: test points, gauges, and test-point kits for reading system pressure; ProTec sleeves, fire sleeve, and ProWrap hose protection; ThinkTank hydraulic tank covers and cleanout covers; hose clamps; O-rings and seals; custom gaskets; and aerosol cleaners and lubricants. Products are described as tested to industry standards including SAE, DOT, and UL. Tompkins supplies fluid power components into automotive, agriculture, construction, and oil and gas applications, and ships to all 50 US states, Canada, and international markets.

Ownership and history

Tompkins Industries started in J.L. Tompkins Sr.'s garage in Olathe, Kansas in 1967, built on a plan to sell reliable products at competitive prices. Over the following decades it grew from a small operation into a fluid power supplier with a national warehouse network and its own manufactured product lines. The company remains privately held; the Tompkins family name persists in its leadership, and no parent company is on record.

The company's largest documented expansion came on January 24, 2011, when Tompkins finalized a merger with Can-Am Hydraulic Products, Ltd. of Mississauga, Ontario. The combined operation became the Tompkins Canada division, with Sean McGuinness, the former President of Can-Am Hydraulic, serving as its General Manager. The merger extended the adapter and fitting line and added inventory and support resources, including free 2D and 3D CAD models and a Hydraulic Adapter Quick Reference Guide, to Canadian customers. Today Tompkins operates from its Olathe headquarters plus roughly a dozen warehouse and branch locations across the United States and the Mississauga site in Canada.

Certifications and quality

Tompkins describes itself as an ISO 9001 certified manufacturer and master distributor, and a third-party fluid power listing records the certification at the current ISO 9001:2015 revision. The certificate date is not published on the company pages reviewed here, so the currency of the cycle is reported as a claim rather than a dated fact. The company states its hydraulic fittings meet or exceed industry standards and that products are tested and certified to SAE, DOT, and UL requirements. Buyers evaluating a distributor of this kind typically confirm the current certificate and scope directly, alongside standard PPAP documentation where a program requires it.

Locations

Tompkins runs a distribution footprint built for regional stock availability rather than a single central plant. The headquarters and main distribution center sit at 1651 East Kansas City Road in Olathe, Kansas, with a parts counter at the same site. Additional branches serve the Midwest and beyond: Kansas City and Saint Joseph in Missouri; Des Moines, Elkhart, and Pella in Iowa; Twinsburg, Ohio; Charlotte, North Carolina; Houston, Texas; Rancho Cucamonga, California; and Portland, Oregon. The Tompkins Canada division operates from Mississauga, Ontario. This spread of stocking locations is what lets the company promise same-day shipping on in-stock items, a service point that matters to equipment builders and maintenance operations weighing nearshoring and lead-time risk.

Sourcing evidence

Tompkins Industries appears in US customs bill-of-lading records with 1,596 sea shipments on file, the most recent dated September 25, 2026, which places it among the actively importing fluid power distributors. The recorded foreign suppliers are the kind a master distributor of hydraulic fittings and hose would use: Ningbo Ningji Yuli Fluid Equipment and Hy Tech Engineers in Asia, Polyhose India, and Sears Industrial. That inbound mix, fittings and hose components brought in for domestic distribution, matches the company's stated model of stocking tube fittings and adapters across a national branch network rather than importing finished machinery.

Coverage caveats apply. These are US ocean-freight records only; air, truck, and rail movements, including most US and Canada cross-border flows, do not appear. Some records name freight intermediaries rather than manufacturers, and product categories come from declared manifest codes, which are noisy. Absence of a record is not evidence of absence, and the shipment count reflects what customs data captures, not total procurement.
