The Highest Quality O-Rings Available When You Need Them

DESIOR TECHNOLOGY CO.,LTD has served as the leading rubber component manufacturer in China.

  HOW TO ORDER  

DESOR o-rings and Rubber seals are specified by three characteristics: size, hardness, and material. Prior to seal specification, please check for availability. We add to our tooling list all the time.

 

Size: Standards are specified by their AS568 or ISO 3601 dash number. Non-standards are referenced by I.D. and C.S. (cross section). Although we only include the AS568 standard sizes in this guide, Desior has a vast inventory of non-standard and metric sizes. And, if you still don't find the size you are looking for, please keep in mind that Desior provides complete customized work to meet your special needs.

 

Hardness: This is specified by a two-digit Shore A durometer number, ranging from 20 (soft) to 90 (hard), depending on the type of elastomer. Our standard durometer is 70 Shore A, except for Viton which is 75 Shore A. Standard durometer tolerance is ±5.

 

Material: Our standard range of materials is designated by a two-letter abbreviation for each elastomer. See the Material Selection Guide for designations and further discussions of materials.

 

 Provide Us With The Following When Ordering: 

 ● Quantity of o-rings.

 ● Size by AS568 dash number, or I.D. and C.S., if ordering a non-standard.

 ● Material by hardness and two-digit material abbreviation.

 

 Examples: 

 ● Standard O-Ring: If you were to order 100,000 pieces of an AS568-110 in 70 durometer Silicone your order would read: 100,000 -110 (dash number) 70SH

 ● Non-Standard: If you were to order 30,000 pieces with an internal diameter of .144″ and a cross section of .025″ 70 durometer Buna-N your order would read: 30,000 .144 I.D. x .025 C.S. 70BN.
