Product Details

The ORING-138 is an AS568 standard dash size -138 O-ring with a 2-1/8" (2.112") inner diameter, 2-5/16" (2.320") outer diameter, and a 3/32" (0.103") cross-section width. Commonly referred to as a cap O-ring, it is designed to create a reliable compression seal in grooved fittings, caps, plugs, and ported connections across automotive, marine, powersports, hydraulic, and industrial applications.

Key Specifications:

  • Dash Size: AS568 -138
  • Inner Diameter (ID): 2-1/8" / 2.112"
  • Outer Diameter (OD): 2-5/16" / 2.320"
  • Cross Section: 3/32" / 0.103"
  • Standard: AS568 (SAE standard O-ring sizing)

Common Materials Available:

  • Nitrile (Buna-N, NBR): 70 durometer — excellent resistance to petroleum oils, fuels, and hydraulic fluids; ideal for most automotive and powersports sealing applications
  • Silicone: Wide temperature range performance; suited for coolant and low-pressure applications
  • Viton (FKM): Superior chemical and high-temperature resistance for demanding environments

This O-ring conforms to the widely recognized AS568 dash -138 sizing standard, making it a straightforward cross-reference and replacement part. It is suitable for use in hydraulic systems, fuel systems, cooling systems, pneumatic connections, and cap/plug sealing applications where a dependable, compression-style seal is required.

I received my order of Shurflo replacement o-rings very quickly - sooner than expected. Unfortunately, I really only needed 1 or 2 o-rings, but they are only offered in a pack of 10. I'll never use 10 o-rings, so it was wasteful spending. I shopped other companies, and could not find packs of 1 or 2, and Boatplicity was the least expensive for what is available on-line.

The product quality is good, and delivery is fast.

I sent in a return request haven't heard anything back would like to return this item
