Custom O-Ring Enquiries in NBR, HNBR, FKM, EPDM, FEPM or FFKM
FEPM and FFKM O-Ring Enquiries: Define the Grade and Chemical Exposure
| Review item |
Information to provide |
| Compound identity |
Required polymer family and exact grade or performance specification; identify approved alternatives separately. |
| Chemical exposure |
Fluid composition, concentration, additives, cleaning agents and exposure duration. |
| Temperature and pressure |
Normal and peak values, cycle duration and decompression conditions where applicable. |
| Dimensions and gland |
Exact standard size or ID and cross-section with tolerances, groove geometry and operating clearance. |
| Documents and availability |
Required compound data and qualification tests, quantity, size and grade availability confirmation. |
Keep FEPM and FFKM under distinct compound identities. AS568 describes dimensions and does not qualify a material for chemical resistance, sour gas or rapid gas decompression. Any pressure capability must be reviewed with the complete gland design and selected compound.
Royal Way accepts custom O-ring enquiries naming NBR, HNBR, FKM, EPDM, FEPM or FFKM. Specify the exact compound and fluid exposure rather than treating a polymer list as one universal seal specification. FEPM and FFKM enquiries require grade, size and availability confirmation for the intended duty before quotation.

Application of the rubber o ring:
For oilfield or hydraulic service, provide the complete fluid or gas composition, additives, cleaning chemicals, temperature, pressure and exposure duration. Include decompression conditions for gas duty. Review the exact compound against these requirements; a FEPM or FFKM polymer designation alone does not establish suitability for every chemical or gas environment.
Structure and sizes:
AS568 enquiries by exact dash number and revision; grade and size availability confirmed separately.
Sizes: (ID × C/S) (mm)
Packing and shipping:
Standard export packing, inner plastic bag, outer with carton. Carton in pallets if necessary.
1: Express: DHL,UPS, TNT, FedEx, EMS ect, for urgent and small order.
2: Air shipment: air port to air port or air port to door.
3: Sea shipment: suitable for bulk goods. it will takes more longer time than air shipment.

FAQ
Q1: Are you manufacture or trading company?
We are manufacture. Our factory located in Haimen District, Nantong City, Jiangsu Province.
Q2: How can we guarantee quality?
Agree dimensions, tolerances, exact compound designation and Shore A hardness inspection criteria. Include the required chemical-exposure or gas-service qualification documents and any application tests in the order specification.
Q3: Can I get some samples?
