Raising industry standards

Specially engineered O-rings used on Seal-Lok™ for CNG fittings improve ozone resistance and support the wide temperature ranges and high pressures found in natural gas applications.

Trap Seal

The patented trapezoidal seal of the Seal-Lok tube end prevents the potential of O-ring fallout during shipment and assembly and O-ring pinch, both common issues for ORFS fittings. This advantage over the competition's standard round O-ring increases the productivity of assembly as well as offers the maximum assurance for a leak-free connection. Ultimately, operational and maintenance costs can be avoided.

The benefits of Trap-Seal are:

• Allows for maximum O-ring retention in the CORG groove
• Prevents O-ring pinch during assembly, which prevents costly leaks
• Works in the standard SAE J1453 half-dovetail groove (CORG)
• 90 durometer nitrile

ToughShield (TS1000) Plating

Parker understands the constant battle with corrosion that affect industries such as agriculture, construction, and others – and the costly downtime that comes with it. Parker TFD's steel fittings and adapters come standard with industry-leading TS1000 Plating, providing up to 1,000 hours of corrosion protection at no additional cost, saving customers both time and money.

Parker TS1000 fights against rust causing issues such as:

• System contamination
• Potential leaks
• Maintenance difficulty
• Accelerated corrosion of adjacent components
• Aesthetic quality concerns

Robust Port Stud

O-ring pinch issues can happen with adjustable SAE O-ring boss (ORB) port ends. This is due to thread exposure below the locknut that leads to a deformed backup washer, pinching the O-ring and creating an O-ring extrusion gap with the potential to leak. To fix this, Parker created the patented Robust Port Stud™. With a longer locknut, the Robust Port Stud eliminates exposed threads and the leak potential of adjustable SAE O-ring boss port ends. This enhanced port end comes standard on all Seal-Lok ORFS fittings with an adjustable SAE O-ring boss port end.

The advantages of Parker's Robust Port Stud are clear:

• Easier, mistake-proof assembly
• Eliminates washer damage and potential leaks
• Maintains SAE form, fit and functional requirements

XTR Coating

Parker knows that when connections on customer’s equipment comes in contact with harsh chemicals, especially the nitrogen-based fertilizers that Ag sprayers see, fittings and adapters can become severely corroded which can lead to early failure and unnecessary downtime. XTR specifically combats those corrosive chemicals and stands the test of time.

Benefits of Parker's XTR Coated fittings:

• Compliant with RoHS, ELV, and REACH
• Extends life of connection in harsh chemical conditions
• Secondary paint procedure is not required

Parflange Flanging Equipment

Parker designed its Parflange equipment to make fast, leak-free connections for Seal-Lok tube fittings without brazing or welding. Using an exclusive orbital spindle motion, Parflange produces high-quality, consistent flanges saving both time and money over welding. Parflange units are easy to operate. With multiple power options and a simple tooling change for flanges, Parflange saves time and money on tube assemblies.

No matter the job needs, Parker has a Parflange to meet any specification whether it is a short run job or a long-term production need. and offers a range of equipment options to the job needs.

Three machines are available:

  • Parflange 1025 - Benchtop unit, overall cycle time of 60 seconds, 440V three-phase
  • Parflange ECO 25 - Benchtop unit, overall cycle time of 100 seconds, 110V single-phase power
  • Parflange Pro 50 - Workstation setup with tooling cabinet, overall cycle time 15 seconds, 440V three-phase, high production machine

Seal-Lok ORFS Fittings for Every Application

Whether the needs are for a standard ORFS fitting that exceeds performance requirements, or the application involves extreme temperatures or special chemicals, Parker has taken the industry's most reliable leak-free connection to the next level. Using the many advantages of the ORFS fitting design, Parker has engineered versions to perform in applications with unique demands.


Seal-Lok for CNG ORFS Fittings
are tailored to accommodate unique natural gas attributes, providing a reliable fuel conveyance using an elastomeric seal compound made of hydrogenated nitrile that improves ozone resistance and supports wider temperature and pressure range requirements.

Seal-Lok Xtreme Fittings utilize the ORFS fitting design with a patented metal seal ring to achieve superior tube and hose connections at temperatures as low as -328°F (-200°C) and as high as 1200°F (650°C). Additionally these fittings can withstand pressures of up to 6,000 psi and are corrosion resistant SAE/ANSI 316/316L stainless steel.

State-Of-The-Art Metallurgical Lab

By investing in technologies that allow Parker to test products in conditions which mimic our customers' applications, Parker continues to develop new products and product enhancements that convey fluid without leaks, while providing long-lasting component life without corrosion, even under the harshest conditions.

Globally Available

Seal-Lok ORFS fittings are manufactured and available globally to support the equipment wherever it is used. Seal-Lok is available in a full line of both SAE port ends and metric port ends per ISO 6149 and ISO 9974-1. Parker's worldwide reach makes Seal-Lok ORFS fittings easier to specify and source through an unrivaled industrial distribution globally.

Rapid Service Unit (RSU)

When time is of the essence and jobs depend on strict deadlines, Parker's RSU can deliver. Whether the part urgently needed is standard, an uncommon jump size, or a one-of-a-kind, RSU designs, produces and delivers high-quality hydraulic and pneumatic fittings and adapters to meet tight deadlines. Custom prototypes, pressure testing and tamper-resistant labeling are also available.

Downtime is further minimized with:
