Product Introduction

Custom nitrile and ethylene-propylene rubber rings are supplied against an agreed seal specification. For an O-ring enquiry, identify NBR (nitrile rubber) or EPDM (ethylene-propylene-diene rubber) together with the inside diameter and cross-section. Matching dimensions do not make these materials interchangeable.
 
Select the compound for the actual fluid, temperature and installation conditions. Describe any oil, water, cleaning fluid or mixed-media exposure in the enquiry. Pressure capability and service life depend on the compound and assembly design, so they must be reviewed for the intended application.

Product Description

Nitrile and EPDM Custom Rings: Compound Identification for Replacement Orders

For a replacement order, provide the part number, drawing revision or an identified sample and state the required compound. A photograph or ring color alone cannot confirm the rubber material.

List each inside diameter and cross-section separately with quantity and hardness. If the same size is required in both NBR and EPDM, use separate order lines and clear package labels to avoid mixing the compounds during assembly.

For a custom rubber ring with a non-circular cross-section, provide the full profile drawing instead of specifying only an O-ring diameter. Agree the dimensional tolerances and sample acceptance requirements before production.

	Size: inside diameter (ID) × cross-section (CS), in mm; supply drawing or replacement reference
	Material: specify NBR or EPDM; other compounds available for application review
	Extra  Service:Customized Size/Hardness/Color OEM/ODM Are Acceptable. Custom Packing Also Available.
