AS568 -220, -227, -230 and -231 O-Rings — NBR/FKM 90 Shore A Enquiries

For the listed AS568 dash sizes, specify each size with its own quantity, NBR or FKM compound and nominal 90 Shore A hardness requirement. The dash number identifies dimensions; color and hardness alone do not establish oilfield service suitability.
Size, Compound and Kit Ordering Data

Other relative products:

Hammer union seals: 

Hammer Union Seals are used in hammer union-style pipe connections to establish flow lines and prevent leakage.

Available size : 1", 2", 3", 4" and 5"

Material options include NBR, FKM and HNBR, with brass or stainless support versions for specified union designs. Provide union figure, size, mating geometry and operating conditions. Sour-service suitability requires compound-specific qualification; a material-family name alone is insufficient.

Swab cups:

Select swab cups with tubing/casing dimensions, mandrel fit, fluid, sand conditions and intended load. Confirm the cup design for the well operation before ordering.

MV Style, TA style, TUF style, NUF style and V styles.

Rubber o rings or kits

Specify color coding and package labels together with the compound designation. Keep size, material and hardness identification on the packaging; color is not a substitute for those details.

About Us:

Shanghai Qinuo Industry Co. Ltd

provides enquiries for rubber, plastic and machined industrial components. Include the drawing or sample and the intended service so that the part specification can be reviewed.
For these O-rings, provide oil or process-fluid composition, normal and peak temperature, pressure cycle and the gland clearance under load. Identify static or moving service and any cleaning-fluid exposure separately.
For repeat supply, retain the approved compound designation, hardness tolerance and size list. Require the same specification on each order rather than identifying replacement rings only by color.
Our quality management system is ISO 9001 certified. Specify required material declarations and test documents with the enquiry. Any API-related application requirement needs the specific standard, scope and supporting product evidence.
