NBR, HNBR or Silicone Rubber O-Rings for Specified Hydraulic Grooves
Flexible Rubber O-Rings: Review Hardness, Installation Stretch and Groove Fit
| Installation check |
Information to review |
| Relaxed dimensions |
Inside diameter and cross-section with tolerances, or exact standard size reference. |
| Assembly route |
Largest feature the ring passes over, entry edges, threads and access to the groove. |
| Hardness and compound |
Target Shore A hardness and tolerance for the specified NBR, HNBR or silicone grade. |
| Installed fit |
Groove dimensions, specified squeeze and stretch, with clearance under operating load. |
| Operating duty |
Fluid, temperature, pressure cycle, motion and lubrication where applicable. |
Use the equipment assembly procedure and compatible installation lubricant. Protect the ring from sharp edges and twisting, and confirm seating before operation. Selecting a softer compound solely to ease assembly can change extrusion resistance; review hardness together with pressure and gland clearance.
Royal Way rubber O-ring enquiries in NBR, HNBR or silicone are specified with the mating groove, fluid and installation conditions. For applications where flexibility matters, define the target hardness and required assembly clearance. A softer feel does not establish the material grade or sealing performance; confirm the compound, dimensions and inspection requirements for the actual equipment.

Application of the rubber o ring:
For hydraulic and oilfield equipment, identify the installation route, fluid, temperature and pressure cycle. Include motion and lubrication for moving seals. Select the actual NBR, HNBR or silicone compound against these conditions; sour-gas, food-contact and special decompression requirements need their own qualification.
Structure and sizes:
AS568 enquiries by exact dash number; confirm grade and availability for the requested size.
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.
