Rated 5 out of 5Â by WeeJim Stops any spillages
Had to take a few radiators off, for decoration purposes. So each time I refit and refill I like to add some inhibitor back into the system through the radiator. This kit is brilliant, just remove 1/2" end plug from top of radiator, connect your inhibitor using this kit, then give a squeeze, and Bob's your uncle.

Rated 5 out of 5Â by Hightech Perfect low cost solution.
This product is extremely simple to use (low tech) and very cost effective.
The one area for improvement would be a piece of hose that was at least twice as long. This would allow to attach and invert the bottle of additive easily.
I would recommend partially draining the system until the highest radiator in the system is a couple of inches below the air vent position, then inject additive at this radiator. This will ensure that you do not get any spillage and no loss of additive.

Used this for a sentinel additive, ok but would not fit 15mm connection so had to open out the internal hole to fit the the 1L bottle cap popped off during use as it wouldn't tighten fully to bottle! Not the best quality...

Rated 5 out of 5Â by PlanTec Great value & easy to use
I purchased this set to use on the 1 litre Sentinel cleaner to dose into a towel warmer which had only one bleed valve at the top. Fixed to the 1 litre sentinel bottle no problem then used the hose bit to fill it no problem at all
