Product Questions & Answers

Is this seal somethin' I can use with regular hydraulic fluid, like the kind for tractors?
Question by: Dale J on Apr 15, 2025, 4:15 PM
This seal features a Buna-N rubber compound, which offers good resistance to petroleum-based hydraulic fluids commonly used in mobile and industrial hydraulic cylinders.

Got a 2.25 bore cylinder, is this the right piston seal size or am I mixing up bore and groove?
Question by: Judy R on Apr 30, 2025, 4:14 PM
For sizing, the key detail given here is that it is a piston T-seal made for a 2.25 inch bore and it uses an O-ring groove style setup for standard piston installations. If your cylinder is a 2.25 inch bore and your piston is machined for an O-ring groove style T-seal, the size and style match what this part is built for.

Does this seal hold up alright with regular petroleum-based hydraulic fluid, or do I need something different for that kind of setup?
Question by: Roy C on Nov 7, 2025, 8:50 PM
Buna-N rubber handles petroleum-based hydraulic fluids well, so for standard hydraulic oil applications this seal is a solid fit. The material was chosen specifically for that compatibility, and it's a common pairing in both mobile and industrial cylinder work.
