Convert Ball Lock and Pin Lock Kegs to Push to Connect

Push to Connect style fittings are used in plumbing, to install water filter systems. to install drink dispensers and more.  Some fittings are for liquids only and some are suitable for use in gas applications.

For whatever reason, I generally find it difficult to find the push to connect style fitting I’m looking for.  Getting the exact fitting, that actually works has been elusive to me.  There are a good number of manufacturers, the products have different applications and there are just lot of models available.
