How to Select a Low-Pressure Push-on/Push Lok Hose

How to select a low-pressure push-on/push lok hose  - low pressure push lok hose - Hose Products Division EuropeSelecting a low-pressure hose often means the choice between rubber or thermoplastic. Both offer distinct advantages however, choosing a hybrid hose can maximize all the benefits in one unit.

Low-pressure hoses are used on a wide variety of machines and industrial equipment to supply different types of fluids (e.g. air, water, oil, vacuum, etc.). Hoses are typically featured in different colors to help users identify individual fluid media inside equipment more easily. Other important factors in selection include fast and easy installation of these hoses.

Push-on/push-lok hoses are very easy to assemble. Just push in the nipple into the hose and the connection is ready.

Rubber low-pressure hoses

Rubber hoses require a low nipple insertion force, enabling the user to perform the hose assemblies on-site on the machines, saving time and cost.

This type of hose is also highly flexible. The rubber compound makes the hose very ductile, decreasing the necessary force to bend it. This feature is very important in applications such as handling robots, where the hose flexibility is stressed at the maximum.

Finally, rubber hoses can support high temperatures. The strong grip between the hose inner layer and the hose nipple contour is guaranteed for environmental temperatures ranging from -40°C to 100°C.

Thermoplastic low-pressure hoses

Thermoplastic hoses require a higher nipple insertion force and are less flexible when compared to rubber hoses but they provide a high level of ozone resistance. This enables the long-term use of these hoses under harsh, outdoor environmental conditions (e.g. telehandlers, forklift trucks) as well as inside applications in high ozone areas.

The polyurethane material that is used also permits the offering of brightly colored hoses with a smooth surface.

 

Hybrid low-pressure hoses

Hybrid hoses, that combine a synthetic rubber inner-tube layer and a polyurethane cover layer, have been engineered to include all the advantages of the two materials in one unit. Their nipple insertion force and flexibility are equal to rubber hoses while their ozone resistance is equal to thermoplastic hoses, but it is on the abrasion and torsion resistance side that the hybrid hoses have no rivals.

The extreme resistance of these hoses to wear and tear makes them the ideal choice for use in very tough applications, such as energy chain systems within machine tool or injection molding machines and handling robots.

Exceptional torsion resistance, with more than one million test cycles on a pressure/torsion test bench, ensures a long-life time when used in multiple movement applications (e.g. welding robots within car production).

These hybrid hoses are also resistant to extremes of temperature, offer a smooth surface and are manufactured in a range of bright colors.

Advantages like these have proven the Parker Hybrid Push-Lok Hose 837-PU to be a preferred solution in a wide range of markets. Global leading car manufacturers are among the users that have specified this hose type for use in their car production lines.
