*SPLIT PTFE B/U 1.498X.119X.062” HT FDA

Use item TST1.498X.119X.062 when a PTFE 55D Backup Ring is required for anti-extrusion support behind O-rings in high-pressure hydraulic and pneumatic glands. The item is specified by 119 mm (4.685 inch) ID x 1.5 mm (0.059 inch) CS; 122 mm (4.8 inch) OD, giving buyers a clear dimensional reference for matching the seal to the groove, shaft or bore. The PTFE construction supports chemical resistance, low friction and low surface energy in demanding static sealing applications. It is with a listed temperature range of -65°F (-53.9°C) to 500°F (260°C), which can help narrow material selection for heat, cold or process exposure. The white color and round profile provide a practical visual identifier during receiving, stocking and installation. As a backup ring, it works with a primary O-ring to help limit extrusion into clearance gaps under pressure. The each-unit format supports precise replacement, kitting, resale and job-specific purchasing. Important product identifiers include O-rings, replacement seals, fluid sealing, material compatibility and dimensional fit. It supports customer comparison, distributor cataloging and specification-based selection without relying on pricing, availability or shipping claims.
