Value Collection ZMSCS70130 Silicone O-ring Dash 130 25pk

Product Description

The VALUE COLLECTION ZMSCS70130 is a round cross-section silicone O-ring sized to the Dash 130 standard, with a 1.625-inch inside diameter, 1.813-inch outside diameter, and a 0.094-inch thickness. Rated at 70 durometer (Hard), it is formulated for applications that demand a wide service temperature range, from -80 degrees F to 450 degrees F. White silicone construction provides good dry heat resistance and strong weather and ozone resistance. Mechanical assemblers, HVAC technicians, plumbers, and maintenance professionals install this O-ring in static and low-dynamic sealing applications where thermal cycling is a primary concern.

This O-ring is suited for use in residential and light commercial mechanical systems where sealing against oils, chemicals, and solvents is required, with the understanding that oil resistance is limited compared to nitrile or EPDM compounds. Typical applications include fluid fittings, valve stems, pump housings, and HVAC equipment service ports. The part is sold in a package quantity of 25, making it practical for bench-stock or field-kit restocking. Because silicone resists ozone degradation, it performs reliably in outdoor or ventilated equipment enclosures.

• Good weather and ozone resistance for indoor and outdoor equipment use
• Compatible with oils, chemicals, and solvents — note limited oil resistance relative to nitrile compounds
• Sold in packs of 25 for efficient restocking

Compatibility

Designed as a standard Dash 130 O-ring replacement for any static or low-dynamic sealing application requiring a 1.625-inch inside diameter silicone seal across HVAC, plumbing, and general mechanical equipment.

Installation Notes

Installation should be performed by a qualified technician familiar with the sealing requirements of the host system. De-energize or depressurize the assembly completely before removing the old O-ring. Inspect the groove and mating surfaces for scoring or debris before seating the new ring. Avoid using sharp tools that can nick the O-ring surface, as cuts will compromise the seal.
