Hello, See the attached photo. This is a very handy 3/4" conduit fitting we use in irrigation and lighting when we run wires through walls. It covers the end of the conduit pipe and the hole we drill for the wire. You can remove the rubber cap and inject some sealant. Its fast, works great and is a very clean looking install. They are also made in 1/2" and white in color. My problem is I am about to run out and my local distributor can't get them anymore. They came from a company down in FL. We have made countless attempts to contact the company but have had no luck. Does anybody have a source or any info? Thanks for your help!
