Tompkins Industries Hydraulic Adapters & Fittings

Tompkins Industries is a hydraulic adapter and fluid power manufacturer founded in 1967 and headquartered in Olathe, Kansas. The company is active and engineers precision hydraulic adapters and fittings in SAE, metric, and British Standard Pipe (BSPP and BSPT) configurations, available in brass, steel, and stainless steel from 1/16 inch through 3 inches. Its catalog also covers quick disconnect couplings, test points, ball valves, O-ring seals, flanges, live swivels, and hose protection products. Northern Hydraulics supplies Tompkins Industries adapters, fittings, and fluid power components, with roughly 1,697 Tompkins line items available for order and cross-reference.

Tompkins Industries Product Lines & Series

Tompkins manufactures more than 8,000 adapter configurations across SAE, metric, and British Standard specifications. The two largest ranges we carry are Tompkins adapters and Tompkins hydraulic fittings, both cross-referenced by thread standard, seat, size, and material. Core families include:

• SAE 45 degree adapters and JIC adapters
• BSPP adapters to DIN 3852-2 and ISO 1179-1
• BSPT adapters to DIN 3852-2
• Metric compression fittings to DIN 3852-1 and ISO 9974-1
• NPT adapters and flange adapters
• Brass adapters and fittings
• O-ring Face Seal adapters and flanges
• Quick disconnect couplings in poppet, ball, and drybreak / flat face configurations
• Live swivels and pipe swivel adapters
• Full-sized and mini ball valves
• O-rings and seals: U-seals, piston cups, vee packing, T-seals, and quad rings
• Protec nylon abrasion-resistant hose sleeve, fire sleeve, and ProWrap hose and cable wrap
• Test points and test point kits

The 2011 merger with Can-Am Hydraulic Products Ltd. of Mississauga, Ontario added ball valves and test point fittings that were not part of the earlier Tompkins lineup, broadening the families available for replacement and equivalent sourcing.

Cross-Referencing Tompkins Industries Parts

If you have a Tompkins part number, a competitor adapter, or an obsolete fitting on hand, we can match it to an equivalent across the SAE, metric, BSPP, BSPT, and O-ring Face Seal ranges. Tompkins publishes a cross-reference number system for finding related products, and we use that interchange data alongside thread, seat, and material specs to identify a replacement or equivalent part. Brass, steel, and stainless versions from 1/16 inch to 3 inches can be matched by configuration when an exact catalog number is discontinued or hard to source. Send us the part number, thread type, or a photo of the markings, and we will return a verified equivalent. Request a Tompkins cross-reference quote to start the match.
