Apeks Low Pressure Rubber Hoses

All LP hoses & Inflator hoses are manufactured at the Apeks factory.

Lightweight flexible hoses withstand a burst pressure more than twice that of traditional hoses.

The typical standard hose length for Primary second stage is 75cm, but pleae note that it might vary from manufacturer to manufacturer & potentially even between sizes.

Most regulators use two different fittings, one for low pressure supplied to the second stage & another for high pressure for contents gauges & transmitters, which prevents the wrong hose being inserted into the wrong port. Generally, low pressure uses a 3/8" threaded hose & high pressure uses a 7/16" hose. However, some manufacturers use other sizes (most commonly a 1/2" port) for the low pressure side.
