Ensure the integrity of your seals

Bonded Sleeves


O-Rings on sliding sleeves can be susceptible to damage during traversing ports and because of differential pressure. Bonding the elastomer to the seal housing is an excellent remedy to prevent this potential mode of failure. At K.C. Seals, our extensive experience with metal prep, bonding agents, and curing parameters means you can feel confident in the integrity of the rubber to metal bond once your tool is downhole.

Things to consider

At K.C. Seals we handle all the bonding preparation work, compression molding, and post-production. What we don’t currently do in-house is the manufacturing of the inner sleeve; however, we do have established relationships with local machine shops that specialize in this work. Additionally, should you machine the sleeves yourself or prefer to use your own outside machine shop, that works for us as well.

Quality you can rely on


All parts are measured on our Zeiss O-Machine and or Keyence CMM, which utilize optical and contact measurement technology in a comprehensive analysis. The O-Machine includes multi-sensor coordinate measuring, white light sensors for non-contact assessments and extremely accurate 3D scanners.

We follow AQL 2.5 levels 1 and 2 sample size quantities, and all molded parts are manufactured to RMA A2 tolerances. 

What comes with your orders:

  • Every order is sent with either a paper or digital QC document that includes ID, OD, C/S, Height, angles, and any other dimensions your organization feels critical. 


Our rubber and plastic materials supply is diversified amongst the top compounders in North America. Each polymer has been qualified to meet typical exploration and production well conditions, including mechanical, tribological, thermal, and specific immersive properties.

What comes with your orders:

  • Every order comes with an MTR that includes a batch number, cure dates, and a set of mechanical properties.
