Value Collection ZMSCV70048 Viton O-ring Dash 048

Product Description

The VALUE COLLECTION ZMSCV70048 is a Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications across HVAC, plumbing, hydraulic, and industrial fluid systems. With a 4.75-inch inside diameter, 4.875-inch outside diameter, and 0.0625-inch thickness, this Dash 048 O-ring seats into standard AN/AS568 dash-048 grooves. The fluoroelastomer compound delivers a 70-durometer hardness rating, providing a hard, resilient seal with low compression set. Its temperature range of -15 degrees F to 400 degrees F makes it suitable for high-heat service environments where standard nitrile compounds fall short.

This O-ring is commonly installed in petroleum fluid lines, hydraulic circuits, refrigeration service ports, pump housings, and valve bodies. Its wide chemical compatibility and low gas permeability make it a reliable choice in vacuum service applications. HVAC technicians, plumbers, and industrial maintenance professionals regularly use this size in large-bore fittings and flanged connections. The round cross-section profile provides uniform contact stress around the full seating surface.

Installation Notes

Installation should be performed by a qualified technician familiar with the sealing system being serviced. Always depressurize and isolate the system before replacing any O-ring. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant before seating to prevent tearing during assembly. Avoid twisting or rolling the O-ring into the groove, and inspect the groove surface for damage or contamination before installation.
