I am looking for ideas for a connector to draw fluid out of a 5-gallon plas= tic bucket. The liquid, a silicone resin, is quite viscous. I've made thr= eaded fittings for the extendable, disposable spout and cap, but a fragile = thing like that eventually leaks. I'm leaning toward a permanent fitting a= ttached to the disposable lid (which tends not to leak when the bucket is i= nverted for use), but I'd rather have something that doesn't require removi= ng the lid.
I recall using a fitting for a plastic container that consisted of a sharp,= screw-threaded end with a hole through the blade that was "punched" into t= he plastic and turned, and the threads would force the back end of the thre= aded portion (that had a rubber washer) firmly up against the plastic surfa= ce. Even with a thin material like water or turpentine, it didn't leak. I= t was removed when the bucket was empty and used for the next bucket.
Anyone know where I might get SOME device for quick and leak-free connectio= n to a disposable, 5-gallon plastic bucket? Or any other ideas?
