Three different pressure hose assembles are available for high pressure gas connections to both stirred and non-stirred vessels. The standard hose is a 6 foot length with a male, “A” socket connector on one side and a 1/8″  NPT(M) nipple with a 1/4″ NPT(M) bushing on the other end. The “A” socket side of the hose attaches to couplings installed on the inlet valve of all stirred reactors and non-stirred vessels as well as to a side port of the gage block assembly. The choice of either 1/8″ NPT of ¼” NPT on the opposite end of the hose allows for attachment to most gas tank valves, pressure regulators or other gas supply sources.

A495HC Hose

A495HC Pressure Hose

The A495HC Hose Assembly is made of nylon. It is rated for 2500 psi and is very flexible and easy to use with dry, non-corrosive gases (nitrogen, hydrogen and oxygen). Care must be taken to ensure that the nylon hose does not come in direct contact with any hot surfaces on the vessel or heater. One of these hoses is included with each complete Parr Series 4500, 5100, and 5500 Stirred Pressure Reaction Apparatus.

A490HC Hose

A490HC Pressure Hose

The A490HC Hose Assembly is a braided, stainless steel hose with a PTFE lining, rated for 2500 psi. It is reasonably flexible and recommended for use with corrosive gases and liquids, and for applications requiring additional abrasion resistance, but it is not intended for high temperature liquids or gases.

A506HC Hose

A506HC Pressure Tube

The A506HC Tube Assembly is a 6 foot length of 1/8″ OD stainless steel tubing, rated for 7500 psi. This small diameter tubing is “bendable”, but it is not as flexible as the other hoses. It is recommended for corrosive gases, high temperature transfers and other high pressure applications. Special versions of this assembly can be made of other corrosion resistant materials. Larger tubing can be used, but it is rigid rather than flexible.

Special hoses with different lengths or end fittings can be assembled for special orders.
