HNBR and NBR Rubber Packer Elements for Oil Well Tool Replacement
Application
Oil-well rubber packer elements and cup seals in HNBR or NBR are reviewed against the original tool drawing and service conditions. Identify the exact part revision, mounting geometry and sealing mechanism before ordering a replacement. FKM alternatives require separate fluid and temperature review.
We manufacture both Wire Skeleton / Wire Mesh / Wire Frame Packer Cups and Rubber Packer Cups without any mesh.
Nominal application sizes include 3.5, 4.5 and 5.5 inches. Broader cup applications from 1-1/4-inch tubing through 7-inch casing require actual bore and finished seal dimensions; nominal size alone does not identify the replacement part.
Features of the rubber oil packer cups:
1) Specify differential pressure, temperature and fluid composition.
2) Match the replacement to the approved tool and part revision.
3) Confirm finished dimensions and tolerances from the drawing.
4) A requested 150°C (302°F) pressure test needs agreed compound, fixture and acceptance limits.
5) A 30-cycle requirement needs defined pressure range, temperature and dwell times.
6) Large cups, including a requested 30-inch diameter, require drawing and manufacturing review.

Product Description
Cup seals and compression-set packer elements require different lip or setting geometries. Provide the construction on the drawing and identify reinforcement, inserts and mounting hardware where used. Drillability and zonal-isolation performance require complete-tool confirmation.
Other relative rubber products:
Our products are widely used at all kinds of cars, machinery, home appliance, electronic products, electric appliance, stationery, computers, oil equipment, and hardware spare parts.
We also can provide oilfield rubber swab cup
The TA swab cup is a medium-duty, all-rubber variable lip cup that offers greater flexibility under lighter loads.
The MV swab cup is a light-duty, all-rubber cup with multiple flexible, upturned lips for sand-laden fluid applications. Confirm tool and tubing fit before selection.
The V swab cup is a ring-type, single-lip, flexible, all-rubber cup molded on a steel bushing. It is ideal for lifting sand-laden fluids and for light-load swabbing. It is a single version of the MV swab cup.
The TUF swab cup is a flexible, synthetic rubber cup with spring steel reinforcing wires for heavy loads but is flexible enough for light or medium loads.
The UF swab cup is an all-purpose, synthetic rubber cup containing strong, flexible spring steel reinforcing wires.
The J swab cup is a durable, heavy-duty cup with a long, flexible lip and strong steel reinforcing wires which provide a good upstroke seal for lifting heavy loads.
The GW swab cup is a heavy, flexible, single-lip cup reinforced by spring steel wire. The oversized lip creates a good upstroke seal.
