Looking for a much easier way to tighten the inhale and exhale fittings to the head unit? Then take a look at the Hollis Prism 2 Hose Tool.
This nifty tool makes it easy to attach, tighten and especially loosen the hoses.
These are printed with the ABS for a far more sturdier and reliable print.
So say good bye to sore fingers and frustration.
