You're so right. Just went through this x 12.
I just got an order for 12 of these wands, to be special made with 14 gauge stainless.
So an already a durable wand will be made to really last now.
I was to get them in from PMF and finish them with the WP Soft Touch triggers. but once I got a look at how they will come to me,
I cringed at the thought of bending the 3/16 tubing just right and installing the Soft Touch just right so that compression fitting holds up. I've only done this onezie twozie before. Not looking forward to 12 of them in a hurry for this guy, so I turned the job down.
Anyway, the custy knowing full well how stupid compression fittings are - from years of brake line failures - decided to go ahead with these wands cuz they're otherwise so durable; says he'll have local welder finish them with a spot weld at the wraparound hanger so it doesn't move. Good luck.
btw Terry your fix looks absolutely stupid, but like you say, what are you gonna do?
How about splice in a 5" section of flexible pressure line and install a hose crimp on one end for going into the trigger valve and a compression fitting for the other end. Wouldn't look too good but at least wouldn't have to do that surgery down low.
I can't imagine how many of these wands have gone into the trash over the last 30+ years or incurred expensive back & forth shipping charges and welding shop charges just to fix a design flaw that never had to be.
One of my goals this year is to make a really durable wand for multi-truckers, you know with guys who regularly break anvils. Guarantee there won't be metal supply lines, certainly no compression fittings.
