High-Pressure Bridge Plug Elements HNBR and FKM Sealing Solutions
Product Introduction
Bridge plug rubber elements are replacement sealing components for the specified downhole tool model, casing range and element stack. Match the element dimensions, position and compound to the original tool specification. Setting and isolation acceptance depend on the complete tool, casing condition and qualified service limits.
Material Properties
The existing material options include HNBR, FKM and NBR. Specify the grade and hardness for each element position, together with actual fluid, gas exposure, temperature and differential-pressure duty.
HNBR: Review the particular compound for mechanical and wear requirements. H2S, CO2 and decompression exposure require grade-specific qualification.
FKM: Review the specified grade against well-fluid formulation, additives and temperature. Polymer identification alone does not establish acid, gas or complete-tool qualification.
Material Comparison: FKM vs HNBR
While both materials are designed for high-performance sealing, they serve different primary functions:
Mechanical Duty: Specify deformation, tear, wear and extrusion requirements for the actual element geometry and support arrangement. Compare properties of the supplied grades rather than assigning performance solely by polymer family.
Temperature: Confirm continuous and peak limits for the particular compound and tool duty. Specify the compound grade, normal and peak temperatures, fluid composition and exposure duration for each element position.
Fluid Compatibility: Provide completion-fluid formulation, additives, gas composition and exposure duration for compound review.
Deployment Conditions: Include minimum surface and downhole temperatures when reviewing the grade and setting behavior.
Application
Application environment: oil, gas, gas condensate
Related Packer Cup Range: The following packer-cup references are separate product configurations. They do not define this bridge plug element’s dimensions, reinforcement or service acceptance.
Related packer-cup options listed in the existing range include wire-reinforced cups and plain-rubber cups. Confirm construction against each cup drawing; no reinforcement is implied for this bridge plug element.
The existing packer-cup range references tubing and casing sizes from 1-1/4 inch through 7 inch. Quote those configurations separately; confirm this bridge plug element’s actual tool and casing dimensions against its drawing.

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
- TA swab cups are related fluid-lifting products. Specify the original cup profile, insert construction, mandrel dimensions and intended fluid load when requesting a separate quotation.
- MV swab cups use a multi-lip profile in the listed range. Provide the original cup reference, tubing internal diameter, mandrel and solids content to select the separate replacement configuration.
- 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.

FAQ
Question: How is a multi-piece element stack specified?
Confirm the original tool design, number of elements and installation positions. Provide each element’s dimensions, compound and hardness, together with the support and backup configuration. Do not assume all bridge plugs use the same three-piece stack.
Question: How is sour-gas duty reviewed?
Provide H2S and CO2 composition, pressure, temperature and decompression conditions. Confirm the supplied compound qualification and complete-tool acceptance; HNBR or FKM names alone do not establish suitability.
Question: What should be checked before redress?
Use the original tool procedure to inspect element dimensions and condition, support components, casing range and setting requirements. Review actual well conditions and any prior failure with the tool supplier.
Question: How are setting requirements confirmed?
Use the original tool’s element arrangement, setting stroke or force and casing limits. Replacement rubber does not independently establish the setting procedure or differential-pressure rating.
Bridge Plug Element Orders: Identify Every Stack Position
Send the bridge plug manufacturer, model and revision with the original element drawing and BOM. Identify each stack position and its outside diameter, bore, axial length, compound and hardness. Include the intended casing size, weight and internal-diameter range from the tool documentation. Quote related packer cups and swab cups separately so their size lists are not used as substitute dimensions for the bridge plug element.
