Value Collection ZMSCVB75219 Viton O-ring Dash 219 50-pack

Product Description

The VALUE COLLECTION ZMSCVB75219 is a Dash 219 Viton (fluoroelastomer) O-ring sold in a 50-piece pack. It measures 1.313 inches inside diameter, 1.563 inches outside diameter, and 0.125 inches thick with a round cross-section profile. The compound carries a Shore A hardness of 75, placing it in the hard durometer range. Rated for continuous service from -15 degrees F to 400 degrees F, this O-ring is built for demanding sealing applications where heat, petroleum exposure, and chemical compatibility are critical requirements. Licensed trades and industrial maintenance technicians rely on fluoroelastomer seals where standard nitrile compounds fall short.

This O-ring is suited for hydraulic, pneumatic, fuel system, and chemical-process applications where petroleum-based fluids or elevated temperatures are present. The fluoroelastomer base material offers low compression set and low gas permeability, making it a practical choice for vacuum service as well as pressurized fluid sealing in HVAC refrigerant circuits, plumbing assemblies, and industrial equipment. The 50-piece package supports shop-stock replenishment and service van inventory.

Key Features

• Fluoroelastomer (Viton-type) compound with a broad chemical compatibility spectrum
• Temperature range of -15 degrees F to 400 degrees F for high-heat service environments
• Shore A hardness rating of 75 for firm, low-compression-set sealing
• Low gas permeability makes it suitable for vacuum service applications
• Good resistance to petroleum products and petroleum-based fluids
• 50-piece pack supports bulk stock for shop or service vehicle inventory

Compatibility

Designed as a standard Dash 219 O-ring replacement for any application requiring a 1.313-inch ID fluoroelastomer seal compatible with petroleum products, high-temperature service, or vacuum service conditions.

Installation Notes

Installation should be performed by a qualified technician familiar with sealing system requirements. Always de-pressurize and lock out the system before replacing any O-ring in a hydraulic, pneumatic, or refrigerant circuit. Inspect the seating groove for nicks, corrosion, or debris before installing the new seal, and apply a compatible lubricant to the O-ring to prevent roll or pinch during assembly. Do not over-stretch the ring during installation, as this reduces effective cross-section and shortens service life.
