Question by: Carl Y on Dec 21, 2025, 3:38 PM

Got a cylinder with a 2-inch bore that needs a new piston seal. Will this one drop right in, or is there more to fitting it than just the bore size?

Answer by: Customer Support on Dec 23, 2025, 8:42 AM

For a 2-inch bore cylinder, the piston diameter this seal is built around is 1.999 inches, with a tolerance of +0 to -0.005 inches. The groove it sits in needs to be 1.69 inches in diameter. One thing worth knowing is that those piston diameter figures assume you're running without wear rings. If your setup uses wear rings, that dimension won't apply the same way. Get those numbers to match up and you'll have a solid fit.

Question by: Stan G on May 15, 2025, 5:57 PM

Reckon this would fit a cylinder with a 2-inch bore? Don't wanna order the wrong thing again.

Answer by: Customer Support on May 17, 2025, 6:32 AM

That's right, this Style 1800 piston seal is made for a 2-inch bore diameter. It's also got a 1.69-inch groove diameter, so be sure to check that measurement too.

Question by: Melvin W on May 20, 2025, 6:01 PM

got a 2.00 bore cylinder, is this Style 1800 seal the right size for it?

Answer by: Customer Support on May 21, 2025, 9:55 PM

For a 2.00 inch bore, this seal matches that bore size and is meant to run with a 1.69 inch groove diameter. It also lists a piston diameter (F) of 1.999 inch with a +0/-0.005 tolerance, and the bore tolerance is ±0.002 inch, so it is set up for a tight, controlled fit.
