Value Collection ZMSCTST009 Ptfe O-ring Dash 009 50-pack

Product Description

The VALUE COLLECTION ZMSCTST009 is a Dash 009 polytetrafluoroethylene (PTFE) O-ring sold in a pack of 50. PTFE is a chemically inert, low-friction fluoropolymer well suited for sealing applications where standard nitrile or EPDM compounds would degrade. This O-ring measures 0.219 inches inside diameter, 0.343 inches outside diameter, and 0.047 inches thick with a rectangular cross section. It carries a medium durometer hardness rating of 55, making it firm enough to hold a reliable seal under pressure while remaining pliable enough to seat properly. HVAC technicians, plumbers, and equipment service professionals use this style of O-ring in valves, fittings, and instrumentation connections requiring broad chemical and temperature resistance.

This O-ring is appropriate for static and low-dynamic sealing applications across residential and light commercial settings. Its operating range spans -65 degrees F to 500 degrees F, covering both cryogenic service and high-temperature fluid or gas systems. Typical install scenarios include refrigerant system fittings, chemical handling valves, compressed air components, and instrumentation ports where PTFE is specified. The 50-piece pack format suits service vans and shop inventory for technicians who routinely stock common dash sizes.

Key Features

• PTFE construction provides excellent chemical resistance and low-friction sealing across a wide range of media
• Operating temperature range of -65 degrees F to 500 degrees F suits both low-temperature and high-heat applications
• Rectangular cross section in Dash 009 sizing for consistent groove fit
• Medium hardness rating of 55 durometer balances seal integrity with proper compression
• Pack of 50 units supports bulk service inventory and reduces per-unit cost

Compatibility

Designed as a standard Dash 009 O-ring replacement for valves, fittings, and sealing grooves dimensioned to accept a 0.219-inch ID by 0.343-inch OD by 0.047-inch thick rectangular PTFE seal.

Installation Notes

Installation should be performed by a qualified technician following applicable system codes such as IFGC or IPC depending on the fluid service involved. Depressurize and isolate the system completely before replacing any O-ring. Inspect the seating groove for nicks, corrosion, or debris before installing a new seal, as surface defects are a leading cause of premature failure. Avoid using petroleum-based lubricants with PTFE O-rings; use only a compatible assembly lubricant approved for the service fluid.
