Value Collection ZMSCS70367 Silicone O-ring Dash 367

Product Description

The VALUE COLLECTION ZMSCS70367 is a round cross-section silicone O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and industrial equipment. It measures 7.5 inches inside diameter, 7.875 inches outside diameter, and 0.1875 inches thick, conforming to the AS568 Dash 367 standard. The silicone compound provides a broad service temperature range of -80 degrees F to 450 degrees F, making it suitable for high-heat and wide-temperature-swing environments. At 70 Shore A hardness, it offers a firm, durable seal. HVAC technicians, plumbers, and maintenance mechanics install this type of O-ring during equipment service, pump rebuilds, and valve overhauls.

This O-ring is appropriate for use in residential and commercial HVAC systems, water handling equipment, and general industrial machinery where a large-diameter sealing element is required. Its silicone construction gives it good resistance to weather, ozone, and dry heat. It has limited oil resistance, so it is best suited for dry-heat, chemical, or solvent environments rather than heavy petroleum-fluid contact. Each package contains one O-ring, sold individually.

Key Features

• Silicone material rated for continuous service from -80 degrees F to 450 degrees F
• Dash 367 standard sizing: 7.5 inches ID x 7.875 inches OD x 0.1875 inches thick
• 70 Shore A hardness for a firm, durable seal under compression
• Round cross-section profile for standard O-ring groove fitment
• Good resistance to weather, ozone, chemicals, and solvents
• Suitable for applications requiring wide temperature range and dry heat resistance

Compatibility

Designed as an OEM-style replacement or service O-ring for equipment requiring an AS568 Dash 367 silicone seal in HVAC, plumbing, pump, and general industrial applications. Compatible with oils, chemicals, and solvents; limited oil resistance applies.

Installation Notes

Installation should be performed by a licensed HVAC technician, plumber, or qualified mechanic. Always depressurize and de-energize the equipment before removing the old O-ring and seating the replacement. Clean the groove thoroughly and inspect for damage before installation. Do not use petroleum-based lubricants on silicone O-rings; use a silicone-compatible assembly lubricant only.
