I was making a set of these for myself to test for leaks and figured why not make more for everyone else. These are for people that have blow-thru setups with just intake pipes and filters. Remove filters and add these and you can pressure test your setup.
These are 2 1/2" Dia x 2-3" long, ends are bead-rolled and one has a 1/4-18NPT bung welded on for air fitting (not included) If you need any other size or configuration just let me know and I can make it happen.

Price is $34 shipped / Couplers - $4 each / Polished Optional $12.
