About Parker

The Parker Hannifin extensive catalogue includes high-quality brass fittings and valves, rubber and thermoplastic hose and fittings, tube fittings, quick-connect couplings and various assembly tools for hydraulic and pneumatic applications. Parker ball valves maintain and regulate high volume and high-pressure liquid flow and feature an easy-to-operate lever for a secure quarter-turn operation.
The Parker Fittings catalogue comprises Intru-Lok fittings, EO fittings, Triple-Lok fittings, Ferulok fittings, EO-2 fittings and Seal-Lok fittings. The brand's Seal-Lok fittings provide resistance against vibration and over-torque. They feature a flat sealing surface and a patented Trap-Seal design, making this ideal for applications in high pressure, vibration and impulsive environments.

Major Trade Names

CPI union cross fittings allow for easy assembly. Feature a single-ferrule design that creates a dynamic seal on the tube and body with close nut tolerance. Provide accurate tube alignment.

Parker Competitive Advantages

Parker Suparcase Surface Coating (Ferrule-Hardening):

Parker Suparcase Surface Coating (Ferrule-Hardening):

  • Applied to the back ferrule, which then forms a carbon supersaturated surface layer by altering the oxide passive layer
  • Enhances the corrosion resistance and hardness rating of STM 316 stainless steel
  • Does not require high temperatures
  • Seals most aggressive fluids & chemicals to resist internal and external corrosion
  • Allows repeated disassembling and reassembling with no loss of sealing integrity
  • Makes surfaces smooth and free of defects
  • Ensures proper lubrication between parts

Parker ToughShield 1000 Coating (TS1000):

Parker ToughShield 1000 Coating (TS1000):

  • Free your steel fittings from red rust for up to 1000 hours of continuous usage
  • Industry class, patented zinc chromium-6 plating said to fight corrosion 13 times better than the required SAE requirements
  • Ideal for tube fittings and adapters
  • Fights against:
    1. Potential leaks
    2. System contamination
    3. Improper function of adjacent components (valves, pumps & cylinders)
    4. Accelerated corrosion of adjacent components

Parker FastSeal:

Parker FastSeal:

  • Make fast and leak-free tube connections without the need for brazing or flanging equipment
  • Parker's robust bite ring and innovative seal dynamics create a robust flat-face tube connection
  • Pairs with Seal-Lok ORFS fittings or easily converts existing connections to ORFS configuration
  • Complies with SAE J1453 and ISO 19879 standards

What is the standard plating that is used by Parker on their fittings?

Parker tube fittings and adapters feature a proprietary zinc chromium-6 free plating, called ToughShield 1000. It offers up to 1000 hours of red rust corrosion resistance and also prevents corrosion from spreading to the adjacent larger components (valves, pumps, etc) in the system.

Which Parker fittings to use to prevent agricultural corrosion?

Parker offers XTR Coating that fights corrosion caused by nitrogen-based fertilizers. XTR Coating is available on tube fittings and adapters, as well as hose fittings, by request. To get a quote, contact Raptor Supplies.

Does Parker have tube fittings and adapters for alternative fuels like CNG, LNG, LPG and H2?

Absolutely, Parker Seal-Lok O-ring Face Seal fittings have separate product lines available, particularly for CNG, LNG, LPG or H2 alternative fuel applications.

Does Parker offer higher temperature O-rings?

Yes, Parker provides high-temperature 90 durometer FKM (fluorocarbon) O-rings that have a temperature rating of -15 to 400 degrees Fahrenheit.
