High Pressure Hose Information

High Pressure Hoses provide the transport for specialty gas systems and applications with a priority in maintaining pressure capacity and the purity of gas delivered. Selecting the right hose is crucial, as it can have a dramatic impact on the efficiency and safety of your gas application.

Please refer to these two guides, to help you select and maintain your industrial hosing:
Hose Selection Guide
Hose Maintenance Guide

There are several choices of materials to consider when selecting a hose:
Rubber – Inexpensive, high permeation rates, not recommended for high purity applications.
Thermoplastic – Ratermann Mfg. TPL Family of Hoses: Durable, economical, flexible and features a low permeation rate. Not recommended for oxygen use.
PTFE - Ratermann Mfg. FP Family of Hoses: The most popular high pressure hose in use. Commonly found in fill plants across the country. Durable, flexible, and economically priced.
PTFE “Post Sintered” – Ratermann Mfg. FPT Family of Hoses: The “post sintered” process re-bakes the PTFE at a controlled time and temperature, increasing the wall thickness and tightening the molecular bond of the PTFE, which dramatically reduces effusion and diffusion. Economically priced, very flexible, and works well with most gases.
Rigid Metal – Ratermann Mfg. PT Family of Rigid Hoses: Economically priced, reduced flexibility, best suited for stationary applications. Rigid hoses will eventually crack as they are bent and flexed.
All Metal Corrugated Hose – Ratermann Mfg. FPS Family of Hoses: All metal hoses utilize a metal corrugated inner core (typically 316 stainless steel or Monel). Metal hoses feature “zero permeation” or “no gas loss,” which is very important in static gas applications. Metal hose is more costly, and is commonly used with helium and hydrogen. Monel inner core is available for corrosive type gases. Pay close attention to dynamic stress and velocity levels (flow rate) as there are limitations with a metal hose.

Smart Hoses are a Flexible “Safety System” for use in the transfer of high pressure gases and liquids. They are designed to protect against the hazardous effects due to hose rupture and tank pull away. Hose Whipping, Loss of Product, Personal Injury, and Property Damage occurrences can be greatly reduced with the use of this intelligent hose system.

We've got a large inventory of Bulk Hoses and equipment as well. All bulk loading hoses and equipment meet RMI's standard of durability and reliability, to keep your fill plant safe and efficient.
