Am after some 'o'rings and the pincers to fit them.

Where is the best place to get them ? Probably want the 'o'rings in 20's.

Have seen them somewhere but they were selling them individually.

See if you have a local hose specialist - the type who repair and supply hudraulic hoses for plant etc.  They usually carry nearly all your hose/hose clip requirements.

This is where I get my o-clips from

The only downside is the postage costs.
