Scuba Diving Accessory: Tank Valve Protector
A super quick way to stop dust and water blowing into an open tank valve after use. Just pull on and off. Includes a full and empty indicator on each side for simple gas management.
Please note that if you have a din valve you will need the insert to get the best from them.
Just like to reply and say thanks for the astonishing service you have
provided, this courtesy e-mail is the icing on the cake. Rest assured
you'll have my business again and both my dive buddies are now perusing the
catalogue you sent, for a stamp of their own.
Good luck for the future.
