White PTFE full-face flange gasket with four bolt holes

Zoro Select Full Face PTFE Flange Gasket 1" Pipe 1/8" Thick

SKU CH-WP9Q-SHTYT

PTFE flange gasket for 1" pipe handles -450 °F to 500 °F in ANSI Class 300 service

  • PTFE material resists chemicals across a wide temperature range
  • Full-face design with four bolt holes matches ANSI Class 300 flanges
  • Operates reliably from -450 °F to 500 °F
  • 1/8 inch thickness provides consistent sealing for 1-inch pipe
  • White PTFE construction is metal-detectable free for clean applications

Zoro Select PTFE Flange Gasket 1" Pipe

This full-face gasket is built for 1-inch piping systems that require a reliable seal across the entire flange surface. It suits maintenance teams and plant operators working with corrosive or high-purity media where PTFE chemical resistance is essential.

PTFE material with ANSI Class 300 rating

The gasket uses pure PTFE without insert or binder materials, delivering a white, non-metallic sealing surface rated for ANSI Class 300 flanges. Four bolt holes at 3/4 inch diameter align with standard drilling patterns, while the 1/8-inch thickness provides consistent compression behaviour across the 4 7/8-inch outside diameter.

Wide temperature range from -450 to 500 Degrees F

The material remains functional from cryogenic conditions up to 500 Degrees F, covering steam, chemical and refrigeration duties without degradation. No fasteners are included, so installers must supply compatible bolts and follow proper torque procedures. Buyers needing metal-detectable gaskets or integrated fastener kits should select a different product.

Questions about this item

What ANSI class does this PTFE flange gasket match?

It is manufactured for ANSI Class 300 flanges, so it fits bolt patterns and pressure ratings for that class

What are the bolt-hole count, diameter and overall outside diameter?

Four bolt holes each 3/4 in diameter on a 4 7/8 in outside diameter ring

How is this full-face gasket installed and what common mistake should be avoided?

Place it between clean flange faces, insert all four bolts and torque them evenly in a cross pattern; the frequent error is tightening one bolt fully before the others, which can crush the PTFE unevenly and cause leaks
