Value Collection ZMSCE70NSF113 Epdm O-ring Dash 113

Product Description

The VALUE COLLECTION ZMSCE70NSF113 is a Dash 113 EPDM O-ring designed for sealing applications that demand reliable performance under elevated temperatures and exposure to demanding fluid types. Measuring 0.549 inches inside diameter and 0.750 inches outside diameter with a 3/32 inch (0.0937 inch) round cross section, this O-ring carries a 70 Shore A hardness rating and is rated for service from -65 degrees F to 300 degrees F. It is installed by licensed plumbers, HVAC technicians, hydraulic system technicians, and maintenance professionals wherever a dependable EPDM seal is required.

This O-ring is suited for residential and commercial plumbing, steam systems, and hydraulic fluid circuits that use phosphate ester-based fluids. It is specifically noted for excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems. It is also recommended for hot water and steam service lines. The round cross-section profile seats consistently in standard Dash 113 grooves. Each package contains 25 O-rings, sold in multiples of 1 package.

Also suitable for applications involving Skydrol fluids used in commercial aircraft hydraulic systems. NSF 61 approval supports use in potable water contact applications.

Installation Notes

Installation is performed by qualified plumbers, HVAC technicians, or hydraulic system technicians following applicable codes such as the IPC or system manufacturer specifications. De-pressurize and drain the system fully before removing the old O-ring and seating the replacement. Inspect the groove for damage or debris before installation. Do not stretch or twist the O-ring during installation, and avoid using petroleum-based lubricants with EPDM material — use a compatible water-based or silicone-based lubricant only.
