Value Collection ZMSCS70133 Silicone O-ring Dash 133 25 Pack

Product Description

The VALUE COLLECTION ZMSCS70133 is a Dash 133 silicone O-ring supplied in a 25-piece pack. It features a 1.813-inch inside diameter, a 2.000-inch outside diameter, and a 3/32-inch (0.0937-inch) round cross-section thickness. Rated at Shore 70 hardness, this white silicone ring handles a working temperature range from -80 degrees F to 450 degrees F, making it a practical choice wherever wide thermal swing and dry heat resistance are required. Plumbers, HVAC technicians, and industrial maintenance mechanics typically install this part in fluid, chemical, and mechanical sealing applications.

This O-ring is suited for static and dynamic sealing in systems that encounter oils, chemicals, and solvents. Its silicone compound offers good weather and ozone resistance, which makes it appropriate for both indoor mechanical assemblies and outdoor or exposed equipment. The Dash 133 designation follows standard AS568 sizing conventions, allowing straightforward cross-reference and replacement in any application calling for that dash number. Limited oil resistance should be factored into service selection when sustained petroleum-oil immersion is present.

Key Features

• Dash 133 standard sizing: 1.813 inches ID x 2.000 inches OD x 0.0937 inches thick
• Silicone compound rated for -80 degrees F to 450 degrees F continuous service
• Shore 70 hardness for a firm, reliable seal under compression
• Round cross-section profile for consistent groove seating
• Resistant to weathering and ozone degradation
• Compatible with oils, chemicals, and solvents in appropriate concentrations

Compatibility

Designed as a standard Dash 133 replacement O-ring for any static or dynamic sealing application requiring AS568 Dash 133 dimensions in a silicone compound with a Shore 70 hardness rating.

Installation Notes

Shut down and depressurize the system before removing the existing O-ring. Clean the groove thoroughly and inspect for wear or damage before seating the new ring. Avoid stretching the O-ring beyond what is needed for installation, and do not use sharp tools that could nick or cut the sealing surface. Where applicable, consult ASME or system manufacturer guidelines for groove tolerances and compression limits.
