Value Collection ZMSCTFE112 Ptfe O-ring Dash 112 100-pack

Product Description

The VALUE COLLECTION ZMSCTFE112 is a PTFE (polytetrafluoroethylene) O-ring with a round cross section, engineered for sealing applications that demand chemical resistance and wide temperature tolerance. With a 0.5000-inch inside diameter, 0.6880-inch outside diameter, and 0.0937-inch thickness, this Dash 112 O-ring fits standard groove dimensions for that dash size. PTFE material provides near-universal chemical inertness, low friction, and zero water absorption, making it a reliable choice where rubber elastomers would degrade. It is rated for service from -300 degrees F to 500 degrees F. Plumbers, HVAC technicians, and industrial maintenance professionals install these in valve seats, fittings, and fluid system connections.

This O-ring is suited for residential and commercial plumbing, HVAC refrigerant circuits, chemical fluid handling lines, and pneumatic systems where aggressive media or extreme temperatures rule out standard nitrile or EPDM seals. PTFE compounds are commonly specified when system fluids include strong acids, solvents, or oxidizers. The Dash 112 designation indicates a standardized size recognized across fluid power and plumbing industries, simplifying cross-referencing during maintenance and repair. These O-rings ship in a package quantity of 100, making them practical for shop stock or service van inventory.

Key Features

• PTFE construction offers chemical inertness across a broad range of aggressive media
• Rated from -300 degrees F to 500 degrees F for extreme temperature service
• Dash 112 standard sizing for straightforward cross-referencing and replacement
• Round cross section for consistent seating in standard O-ring grooves
• Medium hardness rating (Shore 55) balances flexibility and compression resistance
• Package of 100 units supports shop stock and multi-unit service calls

Compatibility

Designed as an OEM-style replacement O-ring for any application requiring a Dash 112 round cross-section seal in PTFE material, including valve bodies, fittings, and fluid system components machined to Dash 112 groove specifications.

Installation Notes

O-ring installation should be performed by a qualified plumber, HVAC technician, or pipefitter following applicable codes such as the IPC or IFGC. Shut off and depressurize the system fully before removing the old seal and inspecting the groove for damage or contamination. Avoid stretching the O-ring beyond its natural diameter during installation, and do not use petroleum-based lubricants with PTFE seals; use a compatible assembly lubricant if needed. Confirm groove dimensions match Dash 112 specifications before installation.
