Part number TSP234 is an AS568-234 white PTFE (Teflon) 55 Shore D Back-Up Ring with an inside diameter of 2.984 in (75.79 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.262 in (82.85 mm). A back-up ring bridges the extrusion gap so the primary seal holds its shape under load.

PTFE (Teflon) is known for a very wide continuous service temperature range and excellent dielectric properties. The compound resists strong acids and bases, oxidizing media, and steam. Continuous operating temperature is published at -65°F (-53.9°C) to 500°F (260°C).

Typical settings include pharmaceutical and biotech, semiconductor fabrication, and aggressive-media pipelines.

Reference part number TSP234 when ordering; the item is sold individually. Nominal inside diameter is listed as 3 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
