Value Collection ZMSCE70133 Epdm O-ring Dash 133 Pack 50

Product Description

The VALUE COLLECTION ZMSCE70133 is a Dash 133 EPDM O-ring designed for static and dynamic sealing applications where exposure to hot water, steam, or phosphate ester hydraulic fluids is a primary concern. The ring measures 1.813 inches inside diameter by 2.000 inches outside diameter with a 3/32-inch (0.0937-inch) round cross section. Durometer hardness is rated at 70 Shore A, placing it in the hard range for improved extrusion resistance under pressure. The compound delivers a working temperature range of -65 degrees F to 300 degrees F, making it suitable for high-temperature fluid systems. Licensed plumbers, HVAC technicians, and hydraulic system technicians use this seal when system media demands EPDM over nitrile or silicone materials. Sold in a pack of 50.

This O-ring is suited for use in plumbing, HVAC, and industrial hydraulic assemblies where the sealing surface contacts hot water, steam, or phosphate ester fluids such as Skydrol-type aircraft hydraulic fluids. The Dash 133 designation follows standard AS568 sizing, allowing direct cross-reference to groove dimensions in existing designs. Residential and light commercial hot water systems, steam heating components, and fluid power circuits using phosphate ester base stocks are all typical deployment environments. The EPDM compound is not recommended for use with petroleum-based oils, fuels, or aromatic solvents.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified hydraulic system technician following applicable IPC, IFGC, or system OEM service procedures. Shut off fluid supply and relieve all system pressure before removing or installing any sealing component. Inspect the groove and mating surfaces for nicks, burrs, or corrosion before seating the O-ring. Do not lubricate with petroleum-based greases; use only a lubricant compatible with EPDM and the system fluid.
