Hydraulic Rubber O-Rings: Match the Compound to Heat and Pressure Duty
Hydraulic O-Ring Heat and Pressure Review: Specify the Complete Duty Cycle
| Selection item |
Information needed |
| Dimensions and groove |
Exact size, tolerances, groove geometry and clearance under operating load. |
| Temperature cycle |
Continuous temperature, short-duration peaks, cold starts and cycle duration. |
| Fluid exposure |
Hydraulic fluid designation, additives, cleaning fluids and exposure time. |
| Pressure and motion |
Maximum pressure, transient peaks, pressure direction, stroke speed and lubrication for moving applications. |
| Acceptance criteria |
Compound designation, Shore A target and tolerance, dimensional and surface inspection requirements. |
An O-ring has no independent pressure rating without its gland and compound data. Review backup-ring requirements against clearance and pressure direction. AS568 identifies dimensions; it does not certify the compound for hydraulic, sour-gas or heat-resistance duty.
Royal Way rubber O-ring enquiries for hydraulic and oilfield equipment are reviewed against the groove, fluid and operating duty. Specify the inside diameter and cross-section or exact standard size, together with normal and peak temperatures. Select the compound and hardness for the complete gland rather than relying on a general heat-resistant description.

Material
|
NBR, HNBR or FKM enquiries by fluid and temperature specification; EPDM, silicone and other materials require separate compatibility review.
|
|
Hardness
|
Original 20-90 Shore A range reference; agree target hardness and tolerance for the selected grade.
|
|
Feature
|
Pressure-cycle, wear and heat performance depend on the compound and gland design.

Application of the rubber o ring:
For hydraulic equipment, identify the oil formulation, pressure direction, operating clearance and static or moving duty. For oilfield equipment, include gas composition and decompression conditions where relevant. Sour-gas and rapid-gas-decompression suitability require compound-specific qualification; neither hardness nor polymer name alone establishes these capabilities.
Structure and sizes:
AS568 enquiries by exact dash number; confirm size, grade and availability.
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.
