What It Fits
Used in gearbox, pump and motor housings, axle ends and bearing bores. If your parts list or the old seal reads 37mm OD x 10mm Height, 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 bore, apply a thin film of sealant or oil to the outer diameter, and press the cap in square with a flat driver.
Pro Tip: Measure the bore diameter accurately; end caps are sized to the bore OD.

Frequently Asked Questions
Q: How do I know this is the right size?
A: Seals are sized by measurement: shaft / inside diameter, bore / outside diameter and width / height. Measure the shaft and bore, not just the old seal, which may be worn or distorted. This part measures 37mm OD x 10mm Height.
Q: Can I do this repair myself?
A: Yes, with basic hand tools and patience. Clean everything, work without sharp tools near the sealing lips, lubricate before assembly, and press seals in square. The installation notes above walk through the key steps.
Q: When will it ship?
A: It ships from our facility in about 10 business days, then transits by the carrier service you choose.

Dry seals and o-rings pinch, twist and tear going in, and that is a second teardown you did not need. AQUA FLEX is NSF H1 rated and one tube covers dozens of installs.
