Specifications

What It Fits

Used in metric DIN 3852 Form E port fittings on European and Asian hydraulic pumps, valves and machinery. If your parts list or the old seal reads 27.7 x 32.7 x 2mm, this is the size.

Design and Material

Buna-N is the all-round workhorse of sealing: tough, abrasion resistant and the right default for oil, hydraulic and water service.

You Can Do This Repair

Clean the port face, seat the ring in the fitting's recess, and tighten the fitting to its specified torque.

Pro Tip: Always replace the profile seal when a fitting is removed; they are single-use once compressed.
