Value Collection ZMSCS70104 Silicone O-ring Dash 104 50-pack

Product Description

The VALUE COLLECTION ZMSCS70104 is a Dash 104 silicone O-ring designed for sealing applications that demand a wide operating temperature range and reliable dry heat resistance. Measuring 0.125 inches inside diameter, 0.313 inches outside diameter, and 0.0937 inches thick, this round cross-section ring is manufactured from white silicone with a Shore A hardness of 70. Rated from -80 degrees F to 450 degrees F, it maintains its seal in environments where standard nitrile or EPDM compounds would fail. Licensed trades and maintenance technicians use this O-ring in fluid, chemical, and solvent handling assemblies where thermal cycling is routine.

This O-ring suits residential and light commercial plumbing, HVAC, and general mechanical applications requiring resistance to ozone, weathering, and dry heat. It is appropriate for use with oils, chemicals, and solvents within its rated temperature window. Note that oil resistance is limited, so verify compatibility with the specific fluid media before installation. Each package contains 50 pieces, making it practical for field stock or shop inventory. It is not FDA approved, so it is not intended for food-contact or potable water applications without independent verification of local code compliance.

Key Features

• Wide temperature range: -80 degrees F to 450 degrees F continuous service
• Round cross-section silicone construction with Shore A 70 hardness rating
• Good ozone and weather resistance for outdoor or exposed installations
• Compatible with oils, chemicals, and solvents within rated conditions
• 50 pieces per package with no minimum order beyond a single package
• Dash 104 standard sizing for direct cross-reference to OEM seal specifications

Compatibility

Dash 104 O-rings are a standard AS568 size used across plumbing, HVAC, pneumatic, and general fluid-handling equipment wherever a 0.125-inch ID round-section seal is specified. Confirm fluid media and temperature requirements against the silicone compound ratings before installation.

Installation Notes

Installation should be performed by a qualified technician familiar with the host equipment. Shut off and depressurize the system before replacing any O-ring seal. Inspect the groove and mating surfaces for nicks, burrs, or corrosion that could compromise the seal. Avoid twisting or rolling the O-ring during installation; light application of a compatible lubricant helps seat the ring without distortion.
