Value Collection ZMSCS70316 Silicone O-ring Dash 316 25 Pack

Product Description

The VALUE COLLECTION ZMSCS70316 is a round cross-section silicone O-ring sold in a 25-piece pack, designed for static and dynamic sealing applications across a wide range of industrial, mechanical, and trade service environments. With an inside diameter of 0.875 inches, an outside diameter of 1.25 inches, and a thickness of 0.1875 inches, this Dash 316 O-ring meets standard AS568 sizing. The silicone compound supports a working temperature range of -80 degrees F to 450 degrees F, making it well suited for applications requiring reliable dry heat and thermal cycling resistance. Hardness is rated at 70 Shore A. Licensed plumbers, HVAC technicians, and maintenance professionals commonly stock silicone O-rings at this size for routine sealing tasks.

This O-ring is intended for use in systems where exposure to oils, chemicals, or solvents is limited and where wide temperature range performance is the primary requirement. Silicone elastomers offer good weather and ozone resistance, making this part appropriate for outdoor equipment, ductwork connections, and fluid handling assemblies that cycle through high or low temperature extremes. It is not recommended for high-pressure hydraulic oil service. Each order ships in a 25-piece package, suitable for service vans or shop stock replenishment.

Key Features

• Operating range from -80 degrees F to 450 degrees F for wide thermal coverage
• 70 Shore A hardness rating for firm, reliable sealing under compression
• Round cross-section profile for standard groove fitment
• Silicone material provides good weather and ozone resistance
• Sold in a 25-piece pack for shop stock or service kit replenishment

Compatibility

Designed as a standard Dash 316 O-ring replacement for any groove or fitting accepting a 0.875 inches ID by 1.25 inches OD by 0.1875 inches thick round cross-section seal. Compatible with applications involving oils, chemicals, and solvents where silicone elastomer is an approved material; limited oil resistance should be evaluated before use in direct petroleum hydraulic circuits.

Installation Notes

O-ring installation should be performed by a qualified technician following the equipment manufacturer's service procedures. Depressurize and isolate the system before removing the existing seal to prevent injury or fluid release. Inspect the groove for burrs, corrosion, or wear before seating the new O-ring; avoid using sharp tools that could nick the sealing surface. Consult applicable codes such as the IPC or IFGC when replacing seals in pressurized gas or plumbing assemblies.
