Value Collection ZMSCH70FDA027 O-ring Dash 027 Nbr Fda

Product Description

The VALUE COLLECTION ZMSCH70FDA027 is a Dash 027 nitrile butadiene rubber (NBR) O-ring with an inside diameter of 1.301 inches, an outside diameter of 1.438 inches, and a thickness of 0.0625 inches (1/16 inch). It features a round cross section and a Shore A hardness rating of 70, placing it in the hard hardness category. This O-ring carries FDA approval and meets SAE and MIL-Spec standards, making it suitable for food-contact and regulated fluid-handling applications. Plumbers, HVAC technicians, and fluid-system mechanics install this type of seal to prevent leakage at joints, fittings, and valve bodies. Each package contains 10 O-rings.

This O-ring is designed for use with petroleum-based fluids and is rated for a working temperature range of -40 degrees F to 250 degrees F. NBR is the most widely used O-ring elastomer in trade applications because of its excellent resistance to petroleum products, strong compression set performance, and good tear and abrasion resistance. Typical installation locations include hydraulic fittings, fuel system connections, HVAC refrigerant-side components where NBR is appropriate, and plumbing valve assemblies. Note: this O-ring should not be stored in direct sunlight or near motors or other electrical equipment that may generate ozone, as ozone degrades NBR compounds.

Key Features

• FDA approved White BUNA material suitable for food-contact and regulated fluid-handling environments
• Rated working temperature range of -40 degrees F to 250 degrees F
• Shore A hardness of 70 for reliable compression set and sealing force
• Excellent resistance to petroleum products with strong tear and abrasion resistance
• Meets SAE and MIL-Spec standards
• Round cross section; Dash 027 size for straightforward groove and fitting compatibility

Compatibility

Compatible with petroleum-based products and fluids in standard Dash 027 O-ring groove applications. Designed as a direct-fit replacement for any system or fitting specifying a Dash 027 NBR O-ring with a 1.301-inch ID, 1.438-inch OD, and 0.0625-inch cross-section thickness.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system mechanics. Always depressurize and isolate the fluid circuit before removing or installing O-rings. Lubricate the O-ring with a compatible fluid or O-ring lubricant prior to seating to prevent twisting and pinching during assembly. Follow applicable codes such as IPC or IFGC for plumbing and gas-system applications.
