2Pack 1/4" Female NPT and 1/2" Male GHT Bulk Head Pipe Fitting Bulkhead Tank Fitting Coupler Coupling With 4 Silicone gasket

took a long time to find this but it is exactly prefect for what i need it for ..

I got these because I needed to drill a hole through the exterior wall of my Morton building to run an antenna wire through. I HATE drilling holes in any exterior wall, but sometimes one must. My plan was to use these as a sort of strain relief, and to improve my weather seal. Sadly, I had to open up the inside diameter a bit to allow for the cable connector and still ended up with a wire running through a much larger hole, requiring me to squeeze a bunch of silicon sealer into the gap. I still think this is better though and the fittings were well machined and did what they were designed to do.

Item arrived with the baggy having been torn through, so the fittings and some of the washers were all in the shipping bag. Several of these fittings had some surface marring or some minor buggering of the threads, but all in all they’re just fine.Got these for my truck, as I’m planning to build an onboard air system with connections at every wheel. These will make that possible, and I have no doubts that they’ll serve their purpose just fine.

I’m using this product to pass through an antique engine block to supply full flow oil filtering.
