Value Collection ZMSCV70228 Viton O-ring Dash 228 Pack 10

Product Description

The VALUE COLLECTION ZMSCV70228 is a Dash 228 Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications where chemical resistance and elevated operating temperatures are required. With a 2.25-inch inside diameter, 2.5-inch outside diameter, and a 0.125-inch round cross section, this O-ring meets standard Dash 228 sizing. The fluoroelastomer compound delivers a hardness of 70 Shore A, a working temperature range of -15 degrees F to 400 degrees F, and strong resistance to petroleum products. This item is sold in a package quantity of 10.

This O-ring is suited for HVAC, plumbing, hydraulic, and industrial fluid-handling systems where exposure to petroleum-based fluids, fuels, or high heat is a factor. The round cross section fits standard O-ring grooves machined to Dash 228 specifications. Typical installers include HVAC technicians, pipefitters, millwrights, and industrial maintenance mechanics who need a reliable sealing element in demanding service conditions. The low compression set and low gas permeability make it appropriate for vacuum service and high-pressure sealing applications as well.

Key Features

• Fluoroelastomer (Viton-type) compound rated for service from -15 degrees F to 400 degrees F
• 70 Shore A hardness rating — hard durometer for reduced extrusion under pressure
• Good resistance to petroleum products, fuels, and a wide spectrum of chemicals
• Low compression set maintains seal integrity over extended service cycles
• Low gas permeability makes it suitable for vacuum service applications
• Round cross section conforms to standard Dash 228 groove dimensions
• Sold in a package of 10 units (minimum order quantity of 1 package)

Compatibility

Designed as a standard Dash 228 replacement O-ring compatible with petroleum products and systems requiring fluoroelastomer sealing material. Compatible material listed by manufacturer includes petroleum-based fluids.

Installation Notes

Installation should be performed by a qualified technician familiar with sealing component replacement in fluid or pneumatic systems. Depressurize and isolate the system before removing the old O-ring, and clean the groove thoroughly to remove debris or old sealant material. Apply a compatible lubricant to the O-ring during installation to prevent tearing during assembly — use only lubricants rated for fluoroelastomer compounds. Do not stretch the O-ring beyond its design limits or use sharp tools that may nick the sealing surface.
