HILTAP LQC Coupler
HILTAP 3TL SERIES Transfer Loading Safety Quick Coupling
The 3TL Coupling's metal-to-metal wedge seal delivers a leak-free connection without a hammer union. No hammering means less operator strain, faster connections and no more replacing leaky seals. Plus, the 3TL handles fluids under EXTREME temperatures and pressures, making it a high-performance, all-purpose coupling.
EMCO Chemical Distributors Optimizes Chemical-Handling With OPW & Civacon
EMCO Chemical Distributors has more than one million gallons of liquid-storage space at its new chemical-blending facility in Pleasant Prairie, WI. To ensure best-in-class safety and leak prevention in its high-volume fluid-handling applications, EMCO employs more than 500 Kamlok® and Autolok® Quick Disconnect Couplers from OPW Engineered Systems and several Civacon Model 8030 Ground Verification systems.
OPW's Inflatable Hatch Seal
OPW Engineered Systems shows how to maximize vapor recovery and improve safety during open dome loading with OPW's Inflatable Hatch Seal. Increase protection for operators and the environment - especially during hazardous chemical loading.
Drylok Dry Disconnect Coupler Animation
OPW's Drylok™ dry disconnect coupler is designed to safely transfer hazardous liquids. Its unique interlocking handle averts accidental spills by preventing uncoupling while the valve is open.
Success Story: NuStar Energy LP
New 890 Series "Hi-Load" Counterbalances from OPW Engineered Systems
help NuStar Energy optimize railcar-loading operations at its Stockton, CA, USA, terminal.
OPW Engineered Systems Robotic Welder
Designed to produce a consistent, certified X-ray quality weld each and every time, OPW Engineered Systems' new robotic welder will further enhance the product quality and durability of its swivel joints.
HGJ Ground Joint Utlity
Hiltap Fittings has announced that its HGJ Series of Joint Utility Unions is now available in a 1-inch size. HGJ Series Utility Unions can be used as a coupling for most steam, water and standard utility applications. By utilizing a commercially available O-ring seal, HGJ utility unions are interchangeable with most conventional ground joint unions.
OPW Kamvalok® Coupler
OPW Kamvalok® Dry Disconnect Couplings are considered the standard of the industry. Used at liquid transfer points where product loss could occur, OPW Kamvaloks® provide a reliable solution to prevent spillage during connection or disconnection. OPW Kamvalok® Dry Disconnect Couplings are used by manufacturers of paint, lacquers, inks, adhesives, fatty acids, pharmaceuticals, liquid soaps, and many other liquid products. They are particularly well suited for handling petroleum products, solvents, ag-chemicals, vegetable oils, detergents and many acids and caustics.
L90 Series Loading Arm Counterbalance
OPW Engineered Systems L90 Series Counterbalance has been designed for loading arms that require higher spring loads to accommodate longer reaches and additional equipment. The innovative linear spring design does not require the pneumatic system that is typical for loading arms that have a longer reach or additional weight from attachments. Because all of the calibrations done on the L90 are completed at the back of the spring, the operator is never placed in harms way, and a simple turn of the adjusting bolt provides finite adjustments to tune the loading arm to the desired balance point.
Epsilon® Low-Spill Coupling System
EPSILON® is a low spill coupling, based on a double ball valve system integrating a sophisticated safety design. Beyond the common advantages of a ball valve design, EPSILON® provides for product flow through an unrestricted flowpath and double shut-off reliability in the coupling connection.
OPW GT32F Drum
OPW Drum/Tote filling arms are ideal for loading all types of intermediate bulk containers (55 gallon drums, totes).
OPW GT33F Drumloader
Boom style loading arms are an excellent choice for variable reach applications, especially in larger sizes and longer reach where the outboard components can be heavy. Its long reach capability, un-paralleled flexibility and ease of operation make this the most popular Top Loading Arm design.

OPW Loading Systems
The transfer of volatile, valuable, potentially toxic fluids requires highly engineered loading arms, couplers and swivels. OPW Engineered Systems is the global leader in the design and manufacture of products that transfer fluids SAFER, CLEANER, FASTER.
Success Story: SI Group
This success story demonstrates how the SI Group Manufacturing prefers OPW Engineered System's Drylock Disconnect Couplers and Adaptors for their outstanding safety features, with virtually no fluid loss and no exposure.
Drylok™ is designed to safely transfer hazardous corrosive, volatile liquids such as acids, solvents and petrochemicals. An interlocking handle averts accidental spills by preventing uncoupling while the valve is open. And, the unit's flat face minimizes fluid loss, further reducing exposure to risk during operation. Drylok™ is ideal for all kinds of hazardous fluids where product loss is a problem, such as high-pressure lines, high flow rates, slurries, and gases.
Top-Loading Fixed Style
This simple arm incorporates only three swivel planes of rotation and is designed for use in top loading installations where the vehicle is located at a fixed distance from the riser pipe. The two swivel planes at the inlet permit both up-and-down and side-to-side movement of the assembly, and the third swivel plane allows the drop pipe to remain vertical.
Valves can be located inboard or outboard to facilitate loading. With a valve located outboard, dripping of viscous products after loading can be minimized.
This single arm loader is adaptable to tight fill or closed loading when equipped with additional swivel planes of roatation and/or drop hose, along with required outboard coupling, union or fitting.
