KTW Parker® O-rings, Parofluor parts, parker FKM Viton
Canyon Components offers KTW Parker Hannifin® O-rings, Gaskets, KTW Perfluoroelastomer (FFKM) parts, & custom molded parts at competitive prices and with great lead-times.
FKM (Viton®, Fluorocarbon)
KTW FKM compounds, O-rings, gaskets, & custom molded parts exhibit excellent mechanical attributes as well as excellent resistance to high temperatures, mineral oil, ozone, fuels, hydraulic fluids, and many other solvents and chemicals.
Fluorosilicone (FVMQ)
The mechanical and physical properties of KTW Fluorosilicone O-rings, gaskets, & custom molded parts are very similar to silicone. Fluorosilicone O-rings, gaskets, & custom molded parts offer improved flexibility and strength, better resistance to fuels and mineral oil, but reduced hot air resistance.
Silicone (VMQ, PVMQ)
KTW Silicone seals, O-rings, gaskets, & custom molded parts are excellent for extreme temperatures in static applications. Canyon Components carries a range of silicone materials, and we are happy to custom tailor a seal to meet your application requirements!
EPDM (Ethylene Propylene)
KTW EPDM materials, O-rings, gaskets, & custom molded parts can operate over a wide temperature range, and are compatible with glycol fluids that cause problems for most typical elastomeric seals.
NBR (Nitrile, Buna-N)
KTW Nitrile O-rings, gaskets, & custom molded parts are very oil-resistant, have strong mechanical properties, are resistant to wear, and are relatively inexpensive. These properties make Nitrile the most commonly used general purpose O-ring, gasket, & custom molded part material.
PTFE Encapsulated
KTW FEP and PFA encapsulated O-rings consist of an elastomeric core and a seamlessly closed casing of modified PTFE. The elastomer core of encapsulated O-rings is typically made of FKM (Viton) or VMQ (silicone) and guarantees a uniform pre-tensioning at the sealing point.
PTFE (Teflon)
The harshest environments require specialized solutions. Often times, a Canyon Components KTW PTFE O-rings are used in harsh chemical environments. Polytetrafluoroethylene, commonly known as PTFE or Teflon®, is a high-performance fluoropolymer known for its exceptional chemical resistance, low friction, and non-stick properties.
