Value Collection ZMSCS70325 Silicone O-ring Dash 325

Product Description

The VALUE COLLECTION ZMSCS70325 is a round cross-section silicone O-ring sized to Dash 325 dimensions, with a 1.5-inch inside diameter, 1.875-inch outside diameter, and a 0.1875-inch thickness. Silicone compound gives this seal a working temperature range of -80 degrees F to 450 degrees F, making it a reliable choice where wide thermal swings or dry heat resistance are required. Shore hardness of 70 places it in the hard range, providing good dimensional stability under compression. The white color aids visual inspection during assembly and maintenance. Plumbers, HVAC technicians, and industrial maintenance trades install this style of O-ring in static and low-pressure dynamic sealing applications.

This O-ring is suited for use in residential and light commercial plumbing, HVAC equipment, chemical handling assemblies, and general industrial maintenance where exposure to ozone, weathering, or moderate chemical contact is expected. Silicone compound offers good resistance to oils, solvents, and chemicals in many general service applications, though oil resistance is noted as limited. Sold in a package quantity of 25 units, this product suits stocking needs for maintenance shops, service vans, and parts rooms handling recurring seal replacements.

Compatibility

Designed as a standard Dash 325 O-ring replacement for any static or low-pressure dynamic seal application requiring a 1.5-inch inside diameter silicone ring with round cross section.

Installation Notes

Power down or isolate the system and relieve all pressure before removing the existing seal. Clean the O-ring groove thoroughly and inspect for nicks, burrs, or corrosion before seating the new ring. Lubricate the O-ring with a compatible lubricant prior to installation to prevent tearing during assembly. Installation should be performed by a qualified plumber, HVAC technician, or industrial maintenance professional following applicable codes and equipment manufacturer guidelines.
