Value Collection ZMSCE70149 Epdm O-ring Dash 149 Pack 25

Product Description

The VALUE COLLECTION ZMSCE70149 is a Dash 149 EPDM O-ring with a round cross section, designed for static and dynamic sealing applications where exposure to hot water, steam, and phosphate ester hydraulic fluids is a concern. It measures 2.813 inches inside diameter, 3.000 inches outside diameter, and 0.093 inches thick. The compound carries a 70 durometer hardness rating, placing it in the hard range, which helps it maintain dimensional stability under compression across a wide service temperature range of -65 degrees F to 300 degrees F. Plumbers, HVAC technicians, and hydraulic system technicians are the typical installers.

This O-ring is suited for residential and commercial plumbing systems, hydronic heating systems, and industrial hydraulic circuits that use phosphate ester fluids such as Skydrol-type aircraft hydraulic fluid. Its EPDM compound makes it a reliable choice wherever hot water and steam sealing are required. It is sold in a package quantity of 25, making it practical for service shops and contractors stocking common seal sizes for recurring maintenance work.

Compatibility

Compatible sealing media include hot water, steam, and phosphate ester type hydraulic fluids. EPDM is not recommended for use with petroleum-based oils or fuels. Verify groove dimensions and system media before installation.

Installation Notes

O-rings of this type are installed by licensed plumbers, HVAC technicians, or hydraulic system technicians depending on the application. Depressurize and drain the system completely before removing the old seal and installing the replacement. Lightly lubricate the O-ring with a compatible, media-appropriate lubricant before seating it in the groove to reduce the risk of twisting or tearing during assembly. Do not use petroleum-based lubricants with EPDM compounds.
