Metric Hydraulic Adapters

Our hydraulic adapters are made to top quality standards which meet or exceed global standards such as SAE and ISO. Our hydraulic adapters are supplied in one of two body styles, brazed or forged. The more common of the two is the forged style as they have a streamlined look, are often easier to install and are less expensive to manufacture. Although not all fittings are supplied in one style or another, once stock depletes on the brazed they will eventually be phased out of circulation.

We offer a full selection of Metric Hydraulic Adapters and Fittings, including BSPP, BSPT, Metric, and 30° Seat. YH Hydraulic metric compression fittings are highly resistant to vibration and create strong, reliable, leak-free connections. They meet or exceed all SAE, ISO and DIN standards. Their cutting ring design dampens the effects of vibrations on your hydraulic system. Finished in trivalent chromate plating.
