90 Duro NBR Nitrile Rubber Packer Elements For Oil Field Down Hole Tools

90 Duro NBR Rubber Packer Elements for Downhole Tools

NBR nitrile packer elements with a nominal 90 duro hardness designation are reviewed against the downhole tool drawing. Specify the hardness scale, tolerance and measurement conditions before ordering. Match the compound and required deformation to the mating bore, support geometry and operating conditions; hardness alone does not establish pressure capability.

We manufacture both Wire Skeleton / Wire Mesh / Wire Frame Packer Cups and Rubber Packer Cups without any mesh.

Standard packer cups types:

Wire packer cups:Wire-reinforced cups form directional seals. Specify reinforcement, insert geometry and lip orientation against the tool drawing and actual bore. Single, dual or multiple-cup arrangements need assembly-specific review.

Heavy-duty packer cups:Heavy-duty cups may use double-basket reinforcement for repeated movement, such as well washing. Confirm reinforcement geometry, metal treatment, compound and mounting details rather than assuming a universal pressure rating.

All-rubber packer cups:All-rubber cups have no wire reinforcement in the cup body. Confirm lip geometry, compound and any separate mounting insert for the required flexibility and wear conditions.

Threaded packer cups:Threaded cups connect through a specified insert. Provide thread form, size and engagement. Steam service requires compound-specific qualification; high-pressure washing suitability must not be assumed.

Nominal application sizes include 3.5, 4, 4.5, 5, 5.5 and 6 inches; confirm actual bore and finished-part dimensions for each tool. Broader cup ranges and custom sizes require separate drawing review.

Features of the rubber oil packer cups:

1) Specify operating differential pressure, temperature and fluid exposure.

2) Confirm the 90 duro scale and tolerance on the material specification.

3) Match dimensions and required setting or lip deformation to the tool drawing.

4) A requested 150°C (302°F) pressure test needs agreed compound, fixture and acceptance limits.

5) A 30-cycle requirement needs defined loading range, temperature and dwell times.

6) Large cups, including a requested 30-inch diameter, require design and manufacturing review.

Cup seals and compression-set packer elements use different mechanisms and require their own mounting and deformation specifications. Identify the intended construction and the approved NBR compound. Drillability and zonal-isolation performance need complete-tool confirmation.

Other relative rubber products:

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.

Application environment: oil, gas, gas condensate.

Packing and shipment :

1: Express: S.F. ,DHL,UPS, TNT, FedEx 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.

Specifying the 90 Duro NBR Packer Element

Confirm the hardness scale, nominal value and permitted tolerance on the drawing or material specification. Include compound identification and measurement requirements; the 90 duro designation alone does not define every material property.

Provide required deformation or setting movement, support clearances, actual bore and temperature. Review compression and extrusion requirements with the complete tool design instead of selecting a harder compound solely from the pressure value.

Send the tool model, part revision, finished dimensions and oil or gas composition. Agree material and assembly test requirements, dimensional inspection and acceptance records before production.
