Value Collection ZMSCV70029 Viton O-ring Dash 029 25-pack

Product Description

The VALUE COLLECTION ZMSCV70029 is a Dash 029 Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and industrial fluid systems. With a 1.5-inch inside diameter, 1.625-inch outside diameter, and a 0.0625-inch thick round cross section, this O-ring delivers a reliable compression seal in environments where petroleum-based fluids, high temperatures, or vacuum service are present. The fluoroelastomer compound is rated from -15 degrees F to 400 degrees F, making it suitable for demanding thermal cycles. Each package contains 25 O-rings. Installation is performed by licensed plumbers, HVAC technicians, and pipefitters.

This O-ring is appropriate for use in refrigeration service valves, fuel and oil lines, hydraulic fittings, pump housings, and compressor assemblies where a standard Dash 029 groove dimension is specified. The fluoroelastomer material provides compatibility with petroleum products, lubricating oils, and a wide range of chemical media, making it a versatile choice for residential and light commercial mechanical systems. It is not FDA approved and should not be used in potable water or food-contact applications.

Key Features

• Fluoroelastomer (Viton-type) compound rated for continuous service up to 400 degrees F
• Low compression set maintains sealing force over extended service life
• Good resistance to petroleum products, lubricating oils, and hydraulic fluids
• Low gas permeability makes it suitable for vacuum service applications
• Round cross section conforms to standard Dash 029 groove dimensions
• Hardness rated at 70 Shore A for consistent squeeze and seal integrity

Compatibility

Designed as a standard Dash 029 replacement O-ring for any groove machined to accept a 1.5-inch ID by 1.625-inch OD by 0.0625-inch thick round-cross-section seal. Compatible with petroleum products and a wide spectrum of chemical media as noted in the product attributes.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or pipefitter. Depressurize and drain the system completely before removing the old O-ring to avoid fluid release. Lightly lubricate the O-ring with a fluid compatible with both the elastomer and the system media before seating it in the groove. Avoid rolling, twisting, or pinching the O-ring during installation, as deformation can cause immediate or premature seal failure.
