T-Seal, Dash Size 334

T-Seal, Dash Size 334

The TP-032 Piston T-Seal (TP-334-WB) is a wide base piston T-seal sized 2.625" ID x 3.000" OD x 0.424" height, designed to provide non-spiraling, extrusion-resistant sealing up to 5,000 PSI with improved tolerances. Built with a Buna-N rubber seal and hard plastic back-ups, this Wide Base (WB) style is made to fit MIL-5514F O-ring glands and interchange with grooves that use 1 O-ring + 2 back-up rings—so you get high-pressure performance without turning your seal groove into a custom art project.

Ideal For

• Hydraulic pistons needing a 2.625" ID / 3.000" OD seal with wide base stability
• High-pressure cylinder applications up to 5,000 PSI where extrusion resistance is critical
• MIL-standard gland setups using MIL-5514F O-ring glands
• Rebuilds where you want a seal that won’t spiral and won’t try to escape the groove under load
• Systems operating across -35°F to +220°F temperature ranges
