Back Flow Valve for DiffusersAll diffusers regardless of whether they are ceramic, rubber membrane or other type of material should have a back flow valve to prevent water from entering your airline. If you do get water coming back up your airline it can cause compressor issues as every time your compressor has to restart, it has to first push the water out of the airline which requires extra pressure. Secondly water in your airline can freeze during the winter months, which means no air comes out and you put undue pressure on your compressor, which can burn up motors and/or break crankshafts and pistons quickly.
This backflow valve comes with 1/2" female NPT threads on the lower end. Please let us know in the comment section if you need an adapter for 3/8" threads and we'll supply that at no extra charge. The hose barb end fits 3/8", 1/2" and 5/8" airline and attaches to both weighted and non-weighted airline with an included stainless steel hose clamp.

Well build and functions nicely
The products build quality is excellent; in fact, its far superior to this product's competitor, "Batdiary". This mount stays locked in place when i use one hand to mount my phone or remove it. Also, the internal mechanism is much nicer than the Batdiary one and feels like it has tighter and more accurate machining tolerances which should prevent it from rattling like its competitor's did after a couple weeks use.
I highly recommend this product, it is worth the high price tag!

Buy once, cry once
This Offroam phone mount is not the cheapest option, but it is easily the most functional and sturdy one available, especially for second-generation Toyota Tacomas. I went through several plastic phone mounts before this and should have bought this one from the start to save both money and frustration.
Installation was very simple, and it is even easier to use day to day. I like that this mount uses adjustable arms to grip the phone rather than relying on MagSafe. It keeps my phone secure even on rough terrain and offers plenty of flexibility for positioning the phone exactly where you want it.

Top notch mount with high build quality
I love it when I take a chance and spend some extra money hoping for a quality product - and it actually pans out. I bought this for my 2nd gen Toyota Tacoma (2014). The install was fast. Instructions were clear. The mount is ROCK solid and has two points of articulation so I can position my phone well. I couldn't ask for a better product. The price I paid was a little steep for a mount, but if you demand quality then look no further.
