• AP50 medium pressure Inflator Hoses
• Auto Air hoses (post 2009 ONLY)

The hose fitting is reusable. It can be easily removed and re-fitted so that the hose length can be shortened to suit the diver - or repaired if damaged.

Hose Shortening Instruction VideoAUTO AIR FITTING - IMPORTANT NOTE:

The AP50B will ONLY fit the post 2009 smaller bore Auto Air hose (AP50C). The AP50B will NOT fit the pre 2009 large bore Auto Air hose and will not make a safe connection if you attempt to do so.

Pre 2009 Auto Air hoses had different end fittings (no longer in production) which fitted that hose only. If you have a pre 2009 Auto Air hose it is not safe to attempt to re-fit the old obsolete fittings from this hose to a length of new small bore (AP50C) Auto Air hose. Pre 2009 large bore hose is no longer available as replacement bare hose.

See below to identify whether you have the correct end fittings for the AP50C hose.
