Value Collection ZBD9500-019 Viton O-ring Dash 019

Product Description

The VALUE COLLECTION ZBD9500-019 is a Dash 019 Viton O-ring designed for static and dynamic sealing applications across plumbing, HVAC, hydraulic, and fluid-handling systems. With an inside diameter of 0.8125 inches, an outside diameter of 0.9400 inches, and a cross-section thickness of 0.0625 inches, this round-cross-section seal delivers reliable compression seating in grooved fittings and valve assemblies. The Viton (FKM) compound provides resistance to petroleum-based fluids, fuels, and elevated temperatures, making it a dependable choice where standard Buna-N seals fall short. Licensed tradespeople and maintenance technicians install this type of seal during equipment rebuild, valve repair, and preventive-maintenance procedures.

This O-ring is suited for residential and commercial applications where a Dash 019 seal is specified. Typical uses include pump rebuilds, valve stem seals, refrigerant-side fittings, hydraulic fittings, and fuel-system connections that require a fluoroelastomer compound. The hard durometer rating and wide service temperature range make it appropriate for high-heat zones or environments involving aggressive chemical exposure. It is sold individually per package, with a minimum order quantity of 25 units.

Key Features

• Viton (FKM) compound resists petroleum fluids, fuels, and aggressive chemicals
• Rated from -15 degrees F to 400 degrees F for broad service temperature range
• Round cross section provides consistent compression and even groove fill
• Hardness rated at 75 Shore A for firm, reliable seating under pressure
• Dash 019 standard sizing ensures interchangeability with groove-specified assemblies
• Lightweight at 0.01 pounds per unit, minimizing handling impact during bulk repair work

Compatibility

Designed as a standard Dash 019 O-ring replacement for any assembly specifying a 0.8125 inch ID by 0.9400 inch OD fluoroelastomer seal with a 0.0625 inch cross-section thickness.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified maintenance technicians. Always de-energize equipment and relieve system pressure before disassembling any fitting or valve housing. Inspect the groove for nicks, burrs, or contamination before seating the new O-ring. Apply a compatible lubricant to the O-ring prior to installation to prevent tearing during assembly; confirm the lubricant is compatible with Viton compound and the system fluid.
