TP-330

Description & Features

Manufactured by Hercules Sealing Products, this is a piston-type T-seal designed for use in hydraulic cylinders where reliable sealing performance under dynamic conditions is required. T-seals are commonly used in piston applications to provide a low-friction, low-leakage seal in double-acting hydraulic cylinders.

The TP-330 features the characteristic T-shaped cross-section that works in conjunction with energizing backup rings, helping to maintain consistent contact pressure across the sealing surface. This design is well-suited for medium-to-high pressure hydraulic systems where traditional O-rings may extrude or lose sealing integrity over time.

Question by: Donna W on Apr 5, 2026, 7:03 AM

Will this T-seal work alright in a cylinder that sees a good bit of pressure?

Answer by: Customer Support on Apr 6, 2026, 10:59 AM

This T-seal is indeed well-suited for medium-to-high pressure hydraulic systems, where standard O-rings might not hold up as well over time. The design helps maintain sealing integrity under those conditions.
