The one piece high pressure seal

Brawn Seal

Overview

K.C. Seals Brawn® Seal is a compact, double-acting rod or piston seal with almost no dead spots. The profile maintains non-twisting in dynamic applications, as required for many applications in exploration and production. The Brawn® seal is commonly used as a T-Seal replacement, as well as an O-Ring and backup ring replacement because of its high-pressure rating.

Features

• Easy installation
• One-piece high-pressure seal
• Stability in the groove
• Zero pressure trap
• Stress reduction on sealing surface
• Non-Twisting in dynamic applications

Proven Test Data

(HNBR)
• 10,000 Psi max @ 80°C (3 hours)
• Several pressure reversals in that time
• ASTM D395 compression set @ 22 hours at 125˚C = 5%

Quality You Can Rely On

Measurement 

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. 

Materials

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.
