Why Choose Nitrile, Buna-N O-Ring Cord (NBR)?

Nitrile, known as Buna-N or NBR, is a widely used elastomer in sealing applications due to its remarkable resistance to petroleum-based oils and hydrocarbon fuels. Operating efficiently within a temperature range of -40°F to +250°F, it boasts excellent tensile strength and abrasion resistance. Compatible with most dilute acids, silicone oils, lubricants, and water applications, NBR is versatile. However, it is advisable to avoid its use with ketones, aromatic hydrocarbons, and phosphate ester hydraulic fluids.

Calculating the Required O-Ring Cord Length

O-Ring Cord Cut-Length Calculator

To ensure you purchase just the right amount of cord for your needs, we offer an O-Ring Cord Cut-Length Calculator. The formula to calculate the necessary cord length is: ((OD + ID) / 2) x Pi = Length, where Pi = 3.14159, and the Inside Diameter (ID) is derived from the Outside Diameter (OD) minus twice the cross-section (C/S): ID = OD - (2 x C/S).

By providing O-ring cord by the foot, we aim to make your sealing projects more efficient and cost-effective. This flexibility, coupled with our high-quality materials and commitment to excellence, underscores our dedication to making getting O-Rings easy for our valued customers.
