Value Collection ZMSCH90214 Dash 214 Buna-n O-ring 50-pack

Product Description

The VALUE COLLECTION ZMSCH90214 is a Dash 214 O-ring made from Nitrile Butadiene Rubber (Buna-N), the most widely used elastomer in fluid-sealing applications. It measures 1 inch inside diameter, 1.25 inches outside diameter, and 0.125 inches thick with a round cross section. Rated at 90 durometer (extra hard), this O-ring delivers excellent compression set resistance along with strong tear and abrasion resistance. The temperature range of -40 to 250 degrees F makes it suitable for a broad range of operating conditions. Each package contains 50 pieces. Plumbers, HVAC technicians, and hydraulic service professionals install this type of O-ring in systems where petroleum-based fluid exposure is expected.

Buna-N O-rings in the Dash 214 size are commonly used in plumbing fittings, hydraulic cylinders, pneumatic assemblies, refrigeration service valves, and fuel-handling components. The 90 durometer hardness suits high-pressure applications where softer compounds would extrude under load. Compatible with petroleum products, oils, and many hydraulic fluids, this O-ring is a standard replacement in residential and light commercial mechanical systems. The 50-piece package quantity suits service technicians who carry common seal sizes on their trucks for field repairs.

Key Features

• Operating range of -40 to 250 degrees F covers most HVAC, plumbing, and hydraulic service environments
• Round cross section, Dash 214 standard sizing ensures interchangeability with OEM specifications
• Meets SAE and MIL-Spec standards
• Pack of 50 — practical for field service inventory

Compatibility

Compatible with petroleum products, oils, and hydraulic fluids. Designed as a standard Dash 214 OEM-style replacement O-ring for use in plumbing, HVAC, hydraulic, and pneumatic assemblies requiring a 1 inch ID nitrile seal. Not FDA approved; not recommended for food-contact applications.

Installation Notes

Shut off and depressurize the system completely before removing or installing any O-ring seal. Plumbers, HVAC technicians, and hydraulic service professionals should lightly lubricate the O-ring with a compatible fluid or grease prior to installation to prevent tearing during assembly. Avoid stretching the O-ring over sharp edges. Do not store unused O-rings in direct sunlight or near motors and electrical equipment that may generate ozone, as ozone exposure degrades nitrile rubber.
