The VALUE COLLECTION ZMSCS70334 is a Dash 334 silicone O-ring designed for static and dynamic sealing applications that demand a wide service temperature range. Manufactured from silicone with a Shore A hardness of 70, this O-ring measures 2.625 inches inside diameter, 3.000 inches outside diameter, and 0.1875 inches (3/16 inches) thick with a round cross section. It is rated for continuous service from -80 degrees F to 450 degrees F, making it well suited for dry heat resistance applications. Each package contains 10 O-rings. Technicians and maintenance professionals working with fluid, pneumatic, or thermal sealing systems will find this part a dependable OEM-style replacement or new-installation seal.
This O-ring is appropriate for use in HVAC equipment, plumbing assemblies, industrial fluid systems, and chemical handling environments where silicone's weather and ozone resistance is an advantage. The Dash 334 designation follows AS568 standard sizing, so it can be specified by plumbers, HVAC technicians, and industrial maintenance teams by number. Note that silicone has limited oil resistance; verify fluid compatibility before installation in oil-wetted systems. It is not FDA approved and should not be used in food-contact applications.
Designed as an OEM-style replacement or new-installation seal for any application requiring an AS568 Dash 334 silicone O-ring with a 2.625-inch inside diameter and 3.000-inch outside diameter.
Installation is typically performed by licensed HVAC technicians, plumbers, or industrial maintenance mechanics. Always de-energize equipment and relieve system pressure before replacing O-rings. Inspect the groove and mating surfaces for damage or debris before seating the new seal. Do not use petroleum-based lubricants on silicone O-rings; use a silicone-compatible lubricant only.
