Rated 5 out of 5 by from Easy to use Bottle Vent I have installed these Bottle Vents at every point where air may need to be bled off. They are easy to fit and work perfectly and with the addition of a threaded sealing cap they can also prevent "air drawback" where this may be a problem.

Bottle Air Vent or End Feed Air Vent Cap Capillary

My End Feed Air Vent Cap needs replaced. Can I use the Bottle Air Vent? The compression joint of the Bottle Vent is easier than needing to fully drain the system so I can solder the other type on.

Is there a long enough thread on this to allow a flanged backnut to be fitted between the body of the air vent and the compression nut. If so what size of backnut would be required.

How many needed?

I have air in my central heating system. We removed a radiator from the loft as it was no longer needed. Do I need 2 of these for each pipe left up there or just the 1?

oil pipe line

Can you use this vent on a heating oil pipe line between the oil tank & boiler. Thanks.
Asked by: Goodfeller
NO - This is not suitable. I noticed you posted as DIY. Your competent oil technician should fit you a tigerloop or similar. Please don't do it yourself.
