Got a 5.50 inch bore cylinder that needs a new piston seal, will this T-seal work with that size, and what's it made out of?

Question by: Rex R on Jul 8, 2025, 4:21 PM

Right fit for a 5.50 inch bore. The seal itself is Buna-N rubber with hard plastic back-up rings, which gives you good resistance to pressure and wear in hydraulic cylinder applications. The O-ring groove design helps keep everything seated and secure once it's installed.
