Hi Gary We use small diameter quick connectors for our gas tanks. These can also be used for water etc. They are a miniature version of the fittings used on compressed air hoses etc. just pull back the outside ring and there you are. If they hold gas pressure they'll hold water pressures in our boilers.
Oh, before I sign off: Seasons greetings to the whole gang from Austria. Bert ------------------------- Bert & Edmunda [EMAIL PROTECTED]
