Value Collection ZMSCS70FDA330 O-ring Dash 330 Silicone 10pk

Product Description

The VALUE COLLECTION ZMSCS70FDA330 is a Dash 330 silicone O-ring designed for static and dynamic sealing applications that demand wide temperature range performance and reliable dry heat resistance. The ring measures 2.125 inches inside diameter, 2.5 inches outside diameter, and 0.1875 inches thick with a round cross section. Shore hardness is rated at 70, placing it in the hard range. This O-ring carries FDA-compliant material designation, making it suitable for food-processing, pharmaceutical, and sanitary fluid handling environments. It is sold in a package of 10 and installed by plumbing, HVAC, industrial maintenance, and process-equipment technicians.

This O-ring is suited for applications requiring resistance across an extended temperature range from -80 degrees F to 450 degrees F. Red silicone construction provides good weather and ozone resistance. The part sees use in food-grade fluid systems, chemical handling equipment, high-temperature pneumatic connections, and similar applications where FDA-compliant sealing material is required. It performs in contact with oils, chemicals, and solvents, though oil resistance is limited and should be evaluated against system fluid compatibility before installation.

Key Features

• Sold in a pack of 10 with a minimum order quantity of 1

Compatibility

Designed as an OEM-style replacement or service O-ring for Dash 330 groove specifications in plumbing, HVAC, food-processing, and industrial equipment requiring FDA-compliant silicone seals. Compatible with oils, chemicals, and solvents; verify oil-resistance requirements before use.

Installation Notes

Install by a qualified plumbing or mechanical technician following applicable IPC or system manufacturer procedures. De-pressurize and drain the system completely before removing the existing seal. Inspect the groove for debris, scoring, or corrosion before seating the replacement ring. Do not use petroleum-based lubricants with silicone O-rings; use a silicone-compatible assembly lubricant to prevent tearing during installation.
