Value Collection ZMSCS70005 Silicone O-ring Dash 005 100 Pack

Product Description

The VALUE COLLECTION ZMSCS70005 is a Dash 005 silicone O-ring designed for sealing applications that demand a wide operating temperature range and reliable chemical resistance. With an inside diameter of 0.0937 inches, an outside diameter of 0.2187 inches, and a thickness of 0.0625 inches, this O-ring features a round cross section and a hardness rating of 70 Shore A. Sold in a pack of 100, it is well suited for plumbers, HVAC technicians, and industrial maintenance professionals who need a compact, high-temperature-rated seal for repeated-service environments. Silicone construction provides good dry heat resistance along with weather and ozone resistance.

This O-ring is used in residential and light commercial applications where sealing against oils, chemicals, and solvents is required. Its rated temperature window of -80 degrees F to 450 degrees F makes it a practical choice for HVAC components, plumbing fittings, and fluid handling assemblies exposed to thermal cycling. The small Dash 005 profile fits tight-clearance ports and fittings common in refrigeration, gas, and water service. Note that oil resistance is limited; verify compatibility before use in heavy petroleum environments.

Key Features

• Silicone material rated from -80 degrees F to 450 degrees F for wide thermal range service
• Round cross section, 0.0625 inches thick, for consistent sealing in standard O-ring grooves
• 70 Shore A hardness provides a firm seal under moderate compression
• Resistant to weather, ozone, and a broad range of chemicals and solvents
• Dash 005 standard sizing for drop-in replacement in matching O-ring grooves
• Pack of 100 units reduces per-unit cost for shop stock and field kits

Compatibility

Designed as a standard Dash 005 O-ring replacement for sealing applications in HVAC, plumbing, and fluid handling systems where silicone material is specified. Compatible with oils, chemicals, and solvents; limited oil resistance applies in heavy petroleum service.

Installation Notes

O-ring replacement is performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Shut off all fluid flow and depressurize the system before removing the old seal. Inspect the groove for nicks, corrosion, or debris that could compromise the new seal. Do not use petroleum-based lubricants with silicone O-rings unless verified compatible; use a silicone-compatible lubricant to ease installation without damaging the seal.
