Product Questions & Answers

got a 2.50 bore cylinder. are these dimensions meant to fit a 2.223 groove dia and 2.499 piston or am i mixing stuff up

Question by: Cody C on Aug 5, 2025, 3:31 PM

Fit comes down to three numbers on this seal: 2.50 inch bore, 2.223 inch groove diameter, and a 2.499 inch piston diameter. Bore tolerance is ±0.001 inch, and the piston diameter tolerance is +0 / -0.003 inch. One note to watch is the piston diameter dimension is given for pistons without wear rings.

So, I got a cylinder with a 2.5 inch bore. Will this seal fit right in there?

Question by: Scott W on Sep 14, 2025, 10:55 AM

This Style 1600 piston seal is made specifically for cylinders with a 2.5 inch bore diameter. It's designed with tolerances to fit snugly, the bore tolerance is held to plus or minus 0.001 inch.

seal's rated up to 5,000 PSI -- that cover most standard hydraulic cylinder work or is that on the lower end for heavy equipment?

Question by: Freddie W on Nov 12, 2025, 6:13 AM

For the majority of hydraulic cylinder applications, 5,000 PSI is more than adequate. Most industrial and mobile hydraulic systems run well below that ceiling, so this seal handles standard cylinder work without issue. The 15% glass-filled PTFE compound also gives it better wear resistance and dimensional stability than plain PTFE, which matters more in day-to-day duty than the pressure ceiling does for most folks.
