Value Caulks & Sealants

Overview

The VALUE COLLECTION ZMSCTST011 is a PTFE (polytetrafluoroethylene) O-ring designed for static and dynamic sealing applications across plumbing, HVAC, chemical, and industrial systems. Manufactured to Dash 011 sizing, it measures 0.327 inches inside diameter and 0.433 inches outside diameter, with a rectangular cross section and a thickness of 0.048 inches. The durometer hardness rating of 55 (medium) provides reliable compression sealing without excessive deformation under load. PTFE construction delivers broad chemical resistance and an operating temperature range of -65 to 500 degrees F, making it suitable for high-temperature and chemically aggressive service environments. Licensed technicians and tradespeople working with fluid handling or refrigerant systems typically specify this ring where standard nitrile or EPDM materials fall short. This O-ring fits sealing applications in residential and commercial systems where dimensional precision and chemical compatibility are critical. The Dash 011 standard sizing makes it a straightforward replacement or repair component in valve bodies, fittings, flanges, and manifold assemblies. It is commonly installed by plumbers, HVAC technicians, and industrial maintenance professionals working on fuel, chemical, or high-temperature fluid circuits. The rectangular cross section provides increased sealing surface contact compared to standard round-section rings of equivalent dash size. Sold in packages of 50 with a minimum order…
