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.
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.
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.

|BFP||Bronze Filled PTFE. provides better creep resistance than most of the PTFE alloys. It possesses high compressive strength and good wear and sliding properties. Most common applications include piston rings (compressors), bushes, bearings, and wear pads for high compression sliding applications||300°F||2000 psi||15%||0.7 uin/min|
|GFPT||Glass fibre improves the wear properties of PTFE, lowers the deformation under load at both high and low temperatures, and increases the impact resistance while leaving the electrical and chemical characteristics of PTFE|
|300°F||1750 psi||175%||0.5 uin/min|
|BGP||bearing grade PEEK (polyetheretherketone) material, reinforced with carbon fibers and internally lubricated with different proprietary lubricants to improve dry running capabilities. Tribological evaluations under dry running conditions have shown its friction coefficient and wear rate to be much lower than other bearing grade composite materials available in the market. Its extremely low wear rate along with low coefficient of thermal expansion properties make this material an ideal candidate for replacing metal wear components.||600 ° F||18900 psi||3.5 %||1.34 µin/min|
|CGTP||Carbon-graphite Filled PTFE (polytetrafluorethylene) material. Its ability to run under dry or wet conditions along with its low wear rate makes it an ideal high-temperature bearing material. It also offers high load-bearing capability, relative to other fluoropolymers, for many general-purpose industrial applications.||150 °F||2300 psi||105.0 %||0.75 µin/min|
