Value Collection ZMSCE70NSF211 O-ring Dash 211 Epdm

Product Description

The VALUE COLLECTION ZMSCE70NSF211 is a Dash 211 EPDM O-ring designed for sealing applications in hydraulic, plumbing, and fluid-handling systems. It measures 0.796 inches inside diameter, 1.062 inches outside diameter, and 0.125 inches thick with a round cross-section profile. Manufactured from EPDM (ethylene propylene diene monomer) compound at 70 durometer hardness, this O-ring delivers reliable sealing performance across a working temperature range of -65 degrees F to 300 degrees F. Licensed plumbers, HVAC technicians, and hydraulic system mechanics install this part in applications requiring resistance to hot water, steam, and phosphate ester hydraulic fluids.

This O-ring is suited for residential and commercial plumbing systems handling hot water and steam, as well as hydraulic systems using phosphate ester fluids. It is also noted for excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it a fit for aerospace maintenance applications. The NSF 61 listing supports use in potable water system components where applicable. Sold in packages of 10 units, it is well-suited for technicians servicing multiple fixtures or performing batch repairs.

Key Features

• EPDM compound at 70 durometer hardness rated Hard for firm sealing under pressure
• Operating temperature range: -65 degrees F to 300 degrees F
• Round cross-section profile, 0.125 inches thick, for standard groove seating
• Excellent resistance to hot water, steam, and phosphate ester hydraulic fluids
• Rated for Skydrol fluid resistance in commercial aircraft hydraulic systems
• NSF 61 listed for applicable potable water contact applications

Compatibility

Compatible with systems handling hot water, steam, and phosphate ester type hydraulic fluids. Designed as a standard Dash 211 O-ring replacement for hydraulic, plumbing, and fluid-sealing applications requiring EPDM compound.

Installation Notes

Installation is performed by licensed plumbers, hydraulic technicians, or qualified mechanics. Always depressurize the system and relieve all fluid pressure before removing the existing O-ring. Inspect the groove and mating surfaces for scoring or debris before seating the new O-ring. Lubricate with a fluid compatible with EPDM compound — avoid petroleum-based lubricants, which degrade EPDM elastomer.
