APG stocks the TFE030, an AS568-030 white PTFE (Teflon) 55 Shore D O-Ring built to an inside diameter of 1.614 in (41 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.754 in (44.55 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
PTFE (Teflon) is specified here for non-stick, non-contaminating surface characteristics and one of the lowest coefficients of friction of any solid. It resists nearly all industrial chemicals, solvents, and oxidizing media. Rated temperature range runs from -65°F (-53.9°C) to 500°F (260°C) in continuous service.
Maintenance and OEM teams specify it across chemical processing, pharmaceutical and biotech, and aggressive-media pipelines.
Reference part number TFE030 when ordering; the item is sold individually. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
