Value Collection ZMSCE70161 Epdm O-ring Dash 161

Product Description

The VALUE COLLECTION ZMSCE70161 is a Dash 161 EPDM O-ring with a round cross section, sized at 5.5 inches inside diameter and 5.688 inches outside diameter, with a thickness of 0.0937 inches (3/32 inches). Made from Ethylene Propylene Diene Monomer (EPDM) rubber, it provides a reliable static or dynamic seal in fluid and pressure systems. The 70 durometer hardness rating indicates a firm, resilient seal suitable for demanding service environments. Installation is performed by licensed plumbers, HVAC technicians, hydraulic system technicians, and qualified maintenance professionals working on commercial and industrial equipment.

This O-ring is rated for service temperatures from -65 degrees F to 300 degrees F, making it well suited for hot water and steam applications. It is also compatible with phosphate ester type hydraulic fluids, including Skydrol fluids used in commercial aircraft hydraulic systems. Typical applications include sealing flanges, valve bodies, pump housings, and hydraulic fittings in plumbing, HVAC, and industrial fluid-handling systems where EPDM chemical compatibility is required.

Compatibility

Designed for use with hot water, steam, and phosphate ester type hydraulic fluids. Compatible with Skydrol fluids used in commercial aircraft hydraulic systems. Not FDA approved. Verify groove dimensions and fluid compatibility before installation.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified hydraulic systems technician. Shut off fluid supply and relieve all system pressure before disassembling any joint or fitting. Inspect the seating groove for debris, corrosion, or damage prior to installing the new O-ring. Avoid using petroleum-based lubricants with EPDM O-rings, as they can cause swelling and seal failure; use a compatible assembly lubricant only.
