Value Collection ZMSCE70235 O-ring Dash 235 Epdm

Product Description

The VALUE COLLECTION ZMSCE70235 is an EPDM O-ring with a round cross section, designed for static and dynamic sealing in fluid and steam systems. It measures 3.125 inches inside diameter and 3.375 inches outside diameter, with a 0.125-inch cross section thickness. The compound carries a 70 Shore A hardness rating and is rated for service temperatures from -65 degrees F to 300 degrees F. This O-ring is suited for plumbing, HVAC, and industrial sealing applications where resistance to heat, water, and select hydraulic fluids is required. Licensed tradespeople and maintenance technicians install this type of seal during system assembly or scheduled maintenance.

This O-ring is appropriate for residential and commercial systems involving hot water, steam lines, and phosphate ester type hydraulic fluids. It performs well in applications requiring a reliable face seal or groove-seated seal where elevated temperatures and moisture exposure are routine. The Dash 235 designation corresponds to a standard AS568 size, making it straightforward to source as a direct replacement during service calls. It is sold in packages of 25 units.

Compatibility

Compatible with systems and equipment handling hot water, steam, and phosphate ester type hydraulic fluids. Designed as a standard Dash 235 EPDM O-ring for use wherever that size and compound specification is called out. Not FDA approved; verify material suitability for any food, beverage, or potable water contact applications before use.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system mechanics. Shut down the system and relieve all pressure before removing the old seal. Lightly lubricate the O-ring with a compatible lubricant before seating to prevent tearing during assembly. Inspect the groove for nicks, burrs, or old seal material before installing the replacement.
