Value Collection ZMSCVB75142 O-ring Dash 142 Viton

Product Description

The VALUE COLLECTION ZMSCVB75142 is a Dash 142 O-ring manufactured from fluoroelastomer (Viton), designed for static and dynamic sealing applications across HVAC, plumbing, hydraulic, and industrial fluid systems. It measures 2.375 inches inner diameter, 2.563 inches outer diameter, and 0.094 inches thick with a round cross-section. The compound carries a Shore A hardness of 75, placing it in the hard durometer range. It is rated for continuous service from -15 degrees F to 400 degrees F, making it suitable for high-temperature environments where standard nitrile or EPDM compounds fall short. Plumbers, HVAC technicians, and industrial maintenance professionals install these as replacement seals in valves, fittings, pumps, and manifold assemblies.

This O-ring is suited for residential and commercial applications where exposure to petroleum-based fluids, hydraulic oils, fuels, or elevated temperatures is a factor. Its fluoroelastomer construction provides low compression set and low gas permeability, which makes it a reliable choice for vacuum service and refrigerant-side sealing. Each package contains 10 O-rings. The Dash 142 designation follows the AS568 standard sizing system, allowing straightforward cross-reference when sourcing replacements.

Key Features

• Shore A hardness of 75 for a firm, low-compression-set seal
• Good resistance to petroleum products, hydraulic fluids, and a wide spectrum of chemicals
• Low gas permeability — suitable for vacuum service applications
• Round cross-section, Dash 142 per AS568 sizing standard
• Sold in a package of 10 units

Compatibility

Designed as an OEM-style replacement or maintenance-stock O-ring for any application requiring an AS568 Dash 142 fluoroelastomer seal. Compatible with systems that handle petroleum products and other fluids consistent with Viton-rated service. Not FDA approved — not suitable for food-contact or potable-water applications.

Installation Notes

Installation should be performed by a qualified technician familiar with the system being serviced. De-energize, depressurize, and isolate the assembly before removing the old O-ring. Inspect the groove for burrs, scoring, or contamination prior to installation; clean mating surfaces with a compatible solvent and allow to dry. Apply a thin film of compatible lubricant to the O-ring before seating to prevent rolling or tearing during assembly — use only lubricants rated compatible with fluoroelastomer compounds.
