Value Collection ZMSCH70FDA113 O-ring Dash 113 Buna-n Fda

Product Description

The VALUE COLLECTION ZMSCH70FDA113 is a Dash 113 O-ring manufactured from Buna-N (Nitrile Butadiene Rubber) with a round cross section. It measures 0.549 inches inside diameter, 0.75 inches outside diameter, and 0.0937 inches thick. Rated at 70 Shore A hardness, it is classified as a hard elastomer. The white color and FDA-approved status make it suitable for applications where food-contact compliance is required. Buna-N is the most widely used O-ring elastomer in the trade, offering excellent resistance to petroleum products, strong compression set retention, and good tear and abrasion resistance. Plumbers, HVAC technicians, and mechanical service professionals install this type of seal regularly in fluid and gas system maintenance.

This O-ring is suited for residential and commercial applications involving petroleum-based fluids, hydraulic systems, fuel handling, and general mechanical sealing tasks. Its FDA-approved, white Buna-N compound makes it a common choice in environments requiring compliance with food-grade or sanitary standards. The working temperature range of -40 degrees F to 250 degrees F covers most standard plumbing, HVAC, and light industrial service conditions. It meets SAE and MIL-Spec standards. Each package contains 25 pieces, sold with a minimum order quantity of 1.

Key Features

• Buna-N (Nitrile Butadiene Rubber) compound — excellent resistance to petroleum products and hydraulic fluids
• FDA approved — white compound suitable for food-contact and sanitary applications
• 70 Shore A hardness — rated as hard, providing reliable compression set performance
• Temperature range: -40 degrees F to 250 degrees F
• Round cross section, Dash 113 sizing — 0.549 inches ID, 0.75 inches OD, 0.0937 inches thick
• Meets SAE and MIL-Spec standards
• Resistant to ozone degradation when stored properly — keep away from direct sunlight and ozone-generating electrical equipment

Compatibility

Compatible with petroleum products and petroleum-based fluids. Designed as a standard Dash 113 O-ring replacement for use in plumbing, HVAC, fuel system, hydraulic, and general mechanical sealing applications where a Buna-N compound is specified.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified mechanical service professionals. Always depressurize and drain the system before replacing an O-ring seal. Inspect the groove and mating surfaces for scoring or debris before seating the new ring. Do not store Buna-N O-rings near motors, compressors, or other electrical equipment that may generate ozone, as this degrades the elastomer over time.
