Product Questions & Answers

So this seal fits into a groove that's 1.233 inches across, right? Just want to make sure I'm reading that correctly.
Question by: Glen H on Nov 8, 2025, 7:20 PM
That's correct. This seal is designed to fit snugly into a groove with a diameter of 1.233 inches. The groove width tolerance is ±0.002 inches, so make sure your groove is within that range for the best fit.

got a cylinder with a 1.625 bore. is this style 1400 seal the right size or am i off a hair
Question by: Dustin F on Jan 13, 2026, 5:41 PM
Fit comes down to the bore, piston, and groove numbers. This seal is sized for a 1.625 inch bore with a ±0.002 inch tolerance, and it pairs with a 1.622 inch piston diameter with a ±0.001 inch tolerance. It also fits a 1.233 inch groove diameter, with the groove width held to ±0.002 inch.

what's the temp range on this seal? got equipment that sees both cold mornings and pretty hot afternoon cycles and just want to make sure it'll hold up
Question by: Daryl C on Sep 13, 2025, 6:42 PM
Rated from -40°F up to 220°F, so it covers a solid spread on both ends. Cold startups and warm running conditions through a full workday should fall well within that window.
