I need to order another hose and want to get some quick releases at the same time but what size is better 14.8mm or 20mm and where's best to order from as I need it for Friday.

20mm stainless are best. Get a bag of viton o rings, a pick set and you'll be sorted for ages

I when with the cheaper ones in the end as I needed 4 pairs and a hose.

No good if using heat everyday like us. Got tired of changing the seals. M22 screw seals last a lot longer.

I haven't got the luxury of heat yet, do you have a some sort of swivel on the end of your hose's?

On the guns. Suttner ST2600's we use. About £38 they are.

We only use the M22 fittings also. Slighty slower to open/close but i find q.r fittings can get dirty and sease up.

Was always greasing them. The males ended up mushrooming and then you'd struggle connecting.
