Please Note: All high pressure hoses use an 'air spool' with two tiny O-rings to mate the swivel connector on the hose to the fitting on the gauge. The air spool is not included with the hose. We recommend replacing the air spool when replacing the hose. The standard spool has the flange in the center but a few SPGs, typically the plastic body ones, may only accept a spool without a shoulder.
Scuba Hose Installation
We recommend that the fitting and installation of all diving hoses should be made by a competent person and using the correct tools. As such we would suggest this is done by a recognised service centre like The Scuba Doctor.
All installation should be made in accordance with the manufacturers recommendations and instructions.
If you are unsure in any way about the installation, please visit The Scuba Doctor for advice.
Scuba Hose Life Warning
Keep in mind that all SCUBA hoses, both rubber or polyester, will fail sooner or later either due to age, storage conditions or handling. Scuba hoses, regardless of brand and materials, require some minimal care. Do not allow hoses to receive prolonged exposure sunlight, as the heat and UV from strong sunlight will significantly shorten the life of the hose. Do not attempt to flush the inside of the hose with any form of solvent or other chemical, new hoses are factory clean and if you have any reason to think they are no longer clean then the hose should be replaced.
Prior to every dive trip you should always pressurise and inspect your hoses for mechanical damage, corroded fittings, bulges and leaks. For more information about the care and maintenance of your dive hoses, please see Caring For Scuba Diving Hoses.
The Scuba Doctor suggests replacing all SCUBA hoses every five years or 500 dives, whichever comes first.
