I have use macroline on everygun I own. I have the same 3 year old piece of it on my spyder that has been there forever. it is easier to cut and mount and if you dont try to take it off your gun when it is aired up (like some people do) then it will last forever.

not true in the least.......I use parker parflex marco lien and it is rated for 800PSI working pressure and 3000PSI burst. if you can blow that up, I invite you to try.
forever.

The hose itself would stand it, but the fittings would not. I dont need to do the test as it has already been performed, the fittings failed.

The hose itself is rated quite highly. However as we all know it is the fittings that fail, this is especially dangerous because the inner part of the push fitting can be propelled at high speeds.

The fittings are only rated at 300psi, the fact that they usually withstand up to 1000psi is a testement to the testing criteria in place. However if you are putting more than 300psi through your fittings then you are running outside the intended operating parameters.

One poor fellow who's macro line burst at Tolouse this year was struck in the eye by part of the elbow fitting and it detached his retina. He was laid up in a French hospital for weeks unable to see or communicate in French.

He is in legal proceedings now due to the fact that macroline (fittings) is sold to be used with pressures upwards of 800psi when it is only rated for 300.

If I were you I wouldnt advise anyone to use macroline, because I woulnt be able to cope if someone sustained an injury because of an inadequate peice of hardware I advised them to get.

Many people over here in the UK have purchased uprated fittings which are visibly much more susbtantial than the normal macro line ones, they are one level above the macroline fittings in terms of operating pressure.
Samples of these have been tested to destruction at >3000 psi.

WOW!

No Excuse - Where does one buy these uprated fittings? What are they called?

ok I will buy that.....you did say the hose is what was rated to 300 PSI. that was my only point :)

Here are the fittings I use. As you can see they are somewhat larger than standard macroline fittings, and the inner collar is a solid tube design. The head swivels in relation to the nut to reduce stress when pressured up.

They are not available from any paintball sources as far as I am aware.
Someone in the UK is supplying these as he has contacts in the engineering industry.

I feel very safe with these fittings, and try to stay away from anyone with a high pressure gun such as an Angel or mag who is still using the old fittings.

I would suggest if you cant find these fittings that you use braided hose.

My apologies.

[xen_100]

if you find out what manufacturer makes these fittings lets us know. I am in no way against more safty (when it only costs a few bucks extra to do it.)

Thank you for all the opinions and information.

If anyone ever tracks down the heavier duty fittings, please post.
Sounds like a promising option.

This is a very informed group and your knowledge and experience is greatly appreciated.

i would go with ss because- ive had macro explode on me....4 times ive also had macro fittings explode and cut open my chin (test firing in back yard, no mask, luckly chinm not eye) and ive had no problems with SS other than it scratching anything it touches, be shure to wrap it with heat shrink tubing, or electrical tpe befor allowing it near your marker. (sorry if these points were previously posted, dint read all posts)

Hi guys, i am the person marketing the high pressure fittings. These fittings have a guaranteed working pressure of 900psi. i have had them professionally tested, and at 4300psi the hose failed but the fittings were as good as new. These fittings also connect and dissconnect far easier than the existing ones, as they have a dual seal system which holds the hose straight in the fitting. The hose i sell with the fittings has a guaranteed working pressure of 1500psi and is similar to the hose supplied by WDP for their Angels.

I am regularly on the P8Talk forum in Britain, under my name Tom Allen, and my e-mail address is [email protected].

I have no problems with supplying anyone in America, as i already export these fittings to several countries.

[No Excuse]

Toma is indeed the guy who I bought my uprated macroline fittings from.

These are as safe as SS line with all the advantages of macroline.

SO WHAT ARE YOU WAITING FOR?

[toma]

No Excuse, thanks for the plug. I shall be putting up a new thread in the dealers forum, describing the fittings and all the safety aspects relating to them tonight. This will include prices.

[Yoda]

It looks like we may have found a nice solution to the higher pressure macroline issues. Great forum.

Thanks for bringing this to our attention toma and No Excuse. I can't wait to get mine and try it out.

[GT]

neither.... I use grease whips

[Yoda]

got 'em

Just got the high pressure fittings and hose from Toma.
Thanks T. for great, fast service even from across the pond.

These are quality parts and I feel very confident using these on guns with higher operating pressure over the current macroline stuff out there. I know there are those that HAVE had issues with other hose/fitting options AND those that HAVEN'T, so your opinions of whether the upgrade is neccessary will vary.

And since I am now an airsmith expert (NOT) ...
I have one last question. What color loctite (or other) thread lock do you recommend for the air fittings?

Thanks again for all the info.
