Value Collection ZMSCH70FDA222 O-ring Dash 222 Buna-n Fda

Product Description

The VALUE COLLECTION ZMSCH70FDA222 is a Dash 222 O-ring manufactured from Buna-N (nitrile butadiene rubber) with an FDA-approved white compound. It measures 1.484 inches inside diameter, 1.750 inches outside diameter, and 0.125 inches thick, with a round cross-section and a Shore A hardness rating of 70. Buna-N is the most widely used O-ring elastomer in trade applications, offering reliable sealing performance across a broad temperature range. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this type of seal in fluid and pneumatic systems where petroleum-based media compatibility is required.

This O-ring is suited for use in residential and commercial plumbing, HVAC refrigerant-adjacent assemblies, hydraulic systems, and fluid-handling equipment where contact with petroleum products is expected. The FDA-approved white Buna-N compound makes it appropriate for applications requiring food-grade material compliance. It is sold in a package quantity of 10, with a minimum order quantity of 1 package. The part meets SAE and MIL-Spec standards, making it appropriate for both commercial trade and light industrial service environments.

Compatibility

Compatible with petroleum products and systems requiring Dash 222 dimensional O-ring seals. Designed for use in plumbing, HVAC, hydraulic, and fluid-handling assemblies where Buna-N elastomer is specified. Not recommended for use in direct sunlight storage conditions or near motors and electrical equipment that may generate ozone.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Shut off all fluid supply and relieve system pressure fully before removing existing seals or installing new O-rings. Inspect the mating groove for burrs, corrosion, or debris before seating the new O-ring. Avoid overstretching the O-ring during installation to prevent damage to the sealing surface.
