Let me show you how I connected these two airlines with a compression fitting.
The tubing, the fitting, and the tools I needed all came in a kit from Rapid Air.
First, I used their cutters to make a clean cut on the ends of both lines.
Next, I tapered the ends with their bevel tool- making three full turns.
This tubing is aluminum with a polyethylene inner and outer layer.
I put the nut and split ring on the tubing– pouring soapy water onto the fitting made it easier to push into place; then I slid the split ring up and hand tightened the nut.
The directions said to draw a line across the fitting and the nut- this way you can keep track of how much you tighten, they want a minimum of a ¾ turn.
You can see I’m within a ¼ turn of being lined back up.
More soapy water on the other end of the fitting; then I repeat the whole process again.
This is not a sponsored ad, but I’m definitely impressed with this system.
The MaxLine tubing is rated to be buried, but they do recommend taping up the fitting to help protect it. Make sure to stay tuned- up next, we’re gonna cover this line with sand and backfill the ditch using a brand-new CAT 265. ‪@hausplans‬
