Product Description

The VALUE COLLECTION ZMSCS70231 is a round cross-section silicone O-ring sized to Dash 231 dimensions, with a 2.625-inch inside diameter, 2.875-inch outside diameter, and 0.125-inch thickness. Rated at 70 Shore hardness, this O-ring is engineered for static and dynamic sealing applications that demand a wide service temperature range, from -80 degrees F to 450 degrees F. Silicone construction provides reliable performance in dry heat environments along with good resistance to weathering and ozone. Licensed plumbers, HVAC technicians, and mechanical tradespeople commonly install O-rings of this type when servicing fluid system connections, valve bodies, and equipment fittings.

This O-ring is well-suited for residential and commercial applications where sealing integrity must hold across extreme temperature swings. It performs in environments exposed to oils, certain chemicals, and solvents, though users should note that oil resistance is limited compared to nitrile or EPDM compounds. Typical installation scenarios include pump seals, manifold connections, and threaded fittings in HVAC, plumbing, and industrial fluid systems. Each purchase includes a package quantity of 10 O-rings.

Key Features

  • Dash 231 standard sizing: 2.625 inches ID, 2.875 inches OD, 0.125 inches thick
  • Silicone material with 70 Shore hardness rating for firm, consistent sealing
  • Operating range of -80 degrees F to 450 degrees F suits wide-temperature-range applications
  • Good weather and ozone resistance extends service life in outdoor or exposed installations
  • Round cross-section profile for standard O-ring groove compatibility
  • Suitable for contact with oils, chemicals, and solvents where limited oil exposure is acceptable

Compatibility

Designed as a standard Dash 231 replacement O-ring for use in HVAC, plumbing, and mechanical fluid systems requiring a 2.625-inch ID silicone seal with a round cross section.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical tradesperson. Always shut off and depressurize the relevant fluid or gas circuit before removing the old O-ring. Inspect the groove and mating surfaces for scoring or debris that could compromise the seal. Avoid overstretching the O-ring during installation; use a compatible lubricant suitable for silicone compounds when seating into the groove.
