You might also check out Innovatek's agb-o-matic
Shown here pushed onto the nose of a HPPS, but it will work with 1046 and 1048 as well.
You have to get rid of the 8mm compression fitting, but the body's threaded for BSPP 1/4, so that's easy.
Note that this is the only
Innovatec push-on res model I recommend. The fancy looking ones (which are more $$ as well) will restrict flow. This one does not - and they've figured out water flow, so it does a really nice job of removing bubbles.
It comes in a couple of colors - the black one is made of softer, more resilient plastic, which is a feature if you're planning to drill the top to install a temp probe.
