The LP series contains low-pressure quick couplings in 06, 07, LP, and SP types. These couplings can be used for a variety of different media including:

• Water
• Fuel
• Compressed air
• Oils

The KL Series is a low pressure, plastic coupling family. Typical for water, fuel, technical gases and midly aggressive media. Part of the Walther quick coupling series, the KL couplings are available in three types including KL-006, KL-012 and KL-030.

The MD series contains medium pressure quick couplings in SG and MD types. These couplings can be used for a variety of fluid media, including lubricating greases and hydraulic oils. They are available in nominal bore sizes ranging from 6-50 millimeters in a variety of material, finish and seal options.

The HP series contains high pressure quick couplings. Typical in steel or stainless steel, the HP series is offered with a variety of options and pressure ratings with bore sizes ranging from 4-50 millimeters. Although grouped in the HP series family, subsea variations of the high pressure series is distinctly different. Specifics on the subsea HP series as well as other couplings can be found in the Offshore & Subsea Technology brochure.

The UF Series contains standard manual couplings that are available in bore sizes ranging from 6-32 millimeters. These non-interchangeable Walther couplings are offered with both square and triangular connection point shapes, and each coupling must be paired with the same shape. They are best suited for low pressure applications with maximum working pressures up to 580 psi.
