Value Collection ZMSCE70265 Epdm O-ring Dash 265

Product Description

The VALUE COLLECTION ZMSCE70265 is an EPDM O-ring with a round cross section, engineered for sealing applications that demand reliable performance across a wide temperature range. It measures 7.75 inches inside diameter and 8 inches outside diameter, with a thickness of 0.125 inches. The Dash 265 designation follows standard O-ring sizing. Made from Ethylene Propylene Diene Monomer (EPDM) with a durometer hardness rating of 70 Shore A (hard), this ring holds its seal in hot water, steam, and phosphate ester hydraulic fluid environments. Plumbers, HVAC technicians, and industrial maintenance professionals install this type of O-ring in high-temperature fluid systems.

This O-ring is suited for residential and commercial plumbing, HVAC, and hydraulic system applications where exposure to hot water or steam is expected. It also carries compatibility with phosphate ester type hydraulic fluids, including Skydrol fluids used in commercial aircraft hydraulic systems. The large diameter makes it appropriate for flanged connections, pump housings, and large-bore valve assemblies. It is sold in a package quantity of six units per order.

Key Features

• EPDM material provides excellent resistance to hot water, steam, and phosphate ester hydraulic fluids
• Rated for operating temperatures from -65 degrees F to 300 degrees F
• 70 Shore A durometer (hard) for positive sealing under compression
• Round cross section and Dash 265 sizing for straightforward groove fitment
• Suitable for Skydrol fluid exposure in commercial aircraft hydraulic systems
• Black color; sold in a package of six O-rings

Compatibility

Compatible with hot water, steam, and phosphate ester type hydraulic fluids including Skydrol fluids. Designed as a standard Dash 265 O-ring replacement for any gland or groove machined to accommodate the 7.75 inches ID by 8 inches OD by 0.125 inches cross section.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified maintenance professional after fully depressurizing and draining the system. Inspect the O-ring groove for damage, debris, or corrosion before seating the new ring. Lubricate the O-ring with a compatible lubricant to prevent tearing during assembly. Never stretch or roll an O-ring over sharp edges without protection, as nicks or cuts will cause premature seal failure.
