Push Lock hose/fittings

[Mcslamma]

The only way I have been able to do it is to start the hose on the push lock barb and throw the assembly in to the deep freezer for a while, take it out shove on and sometimes a second freeze was required, to get it to go on all the way, but sure ain't coming off again without a blade that's for sure..
The fitting shrinks and the rubber don't bite as much I guess, but it worked for me..good luck

Well, finally got all the Push Lock fittings installed. Soaked the hose ends in boiling water for 5 minutes and used dishwashing liquid on the fitting barbs and a little in the hose end. Still took some mighty pushing and a little "fixture" to help steady the 90 degree elbows. Makes for a real clean fire sleeve installation. Somewhat intrigued by the freezer approach, but I was in get it done mode rather than experimenting.
Turns out that I will have to remove the oil cooler to install the fittings into it anyway as the 45 degree fittings will not clear the engine mount to turn them (at least in my installation, your results may vary).

Photos of this type of push lock fitting would be appreciated. I'm new to all of this and I suspect this is in my future.

Great thread.

By holding the fittings in a soft-jawed vice I've been able to install the hose dry without any other help from heat or lubricant. Guess I have strong fingers.

The key is the vice jaws. Summit Racing makes a set of jaws that fit the fittings. I have used them on several race cars and on my Zenith 601. I used a dab of 30wt oil and push them on in one motion. My race cars were high temp oil lines with very high pressure. I'm more into aluminum flared fittings and hard lines now but I still use push lock for fuel lines and oil cooler lines.

I did find this neat tool while looking for a photo of the jaws. I might have to buy one of these babies

That's a great looking tool. If a guy was doing a lot of hoses it would really be nice... I'd like to have one anyway.

My old wrists are still feeling the stress from working those hoses on. If I had any more to install, I would certainly like to have that tool (or maybe John will get one ). I did not find who actually sells it though.

Thank's John, I have now decided to install PTFE (TEFLON) like I have on the fuel.

Do you use hose clamps on the Push Lock fittings as I read somewhere they were not required, I am concerned about the heat when used in the oil system as I used boiling water to install them.

When used with the correct hose, no clamps are used or needed. If you’re a belt and suspender guy, I don’t think it hurts to use a clamp too.
