Guide rings are most typically required in applications where you are looking to prevent metal-to-metal contact. Metal to metal contact in industrial applications can not only cause damage to the working system but can also create larger extrusion gaps in dynamic applications. In dynamic applications, the extrusion gap can become larger as the wear increases. The larger the gap, the larger the possibility of contaminants passing through. This increased extrusion gap can also decrease the pressure rating of the seal, therefore decreasing the overall performance of your primary seal. This is where a Guide Ring can be installed to prevent these problems from occurring. Now, depending on the tolerance of the guide ring, the potential for a decreased pressure rating can be reduced by 30% to 50%. With the highest reduction being offered at the tightest tolerances, we can manufacture Guide Rings to ±0.001 inches tolerance.

Advantages of using a Guide Ring

  • Reduced risk of damage from metal to metal contact
  • High load-bearing capacity
  • Eliminates local stress concentrations, while also eliminating fretting and seizure
  • Decrease friction
  • Prevention of equipment damping from mechanical vibrations
  • Provides protection for your primary seal
  • Reduces hydrodynamic pressure problems in the guide system

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.
