Most of the Higher Fitting catalog interchanges dimensionally with the major hydraulic fitting brands — Parker, Aeroquip, Brennan, Tompkins, Gates, Weatherhead, and others. If you buy or spec by another brand's part number, you don't need to re-engineer anything: send us the numbers, and we return the matching Higher Fitting part for each line.

How our cross-reference works

Hydraulic fittings are built to published standards (SAE J514, J1453, J1926, J518, ISO 8434, DIN 2353), so a correctly crossed part is dimensionally interchangeable. When you send a competitor number we verify four things before we call it a match: thread form and size on every connection, seat or seal geometry, material and plating, and pressure class. If a line doesn't have a clean equivalent, we say so instead of forcing a near-match.

What to send

One line per part: the brand, their part number, and the quantity you buy. A photo or a drawing helps for modified or unusual parts. We reply with a line-by-line table — their number, our number, unit price at your quantity, and stock position — within 24 business hours.
