what size wrench for -10an hose?

[Chris Sawatsky]

What size wrench do I need to tighten a -10an hose onto the fitting? I usually use a crescent, but it's too big to fit in behind the block so I figured I'd get a stubby wrench that fits right. I think it's 25 or 26mm but some real input would be nice

Having a brain fart on the AN "code", but it should be a 5/8's IIRC

-10 would be 5/8" hose not wrench size.

I don't have a set of AN wrenches to throw a set of calipers on to check the size for you.

If you don't have an answer soon, I'll go out to the car in the trailer and check for you.

Mine measure 1.014"

25mm is too small
26mm is a really good fit

1" is too small
1 1/16" is too big ( about .05" too big)

If you already have a 1 1/16" wrench it will work.

If you have to buy a wrench you might as well get an AN wrench. Any industrial hose supply place should have them...no need to get some super high dollar ones off the Sanp-on truck.

1" works, and BTW use the blue hose with the push on fittings. No shame here and also no .028 holes in your finger tips or bloody knuckles.

I'll second the opinion on the push-on hose. Properly protected from mechanical abrasion, it really gets the job done - without being so damned pretty, of course...

yep, I'm rockin the blue hose push-on stuff. in addition to being cheaper than braided, isn't it substantially lighter?

I'm going to hit canadian tire to see if they have a 26mm stubby wrench first. I have some serious doubts that anyone around here would carry AN wrenches in stock

[chuck baader]

Summit has a 5 AN wrench set for 39.95...you shouldn't use regular wrenches for fear of overtighntening and leakage.

Yeah what Chuck said. Stubby would be cool though.

I said 1" would be too small. But it depends on the brand. Some better quality open end wrenches will be closer to their marked size than others. A harbor freight 15/16" would probably be too loose ! Further my fittings aren't new so I figured the anodizing was a little thicker new than it is now.

LOL.. told you guys I was having a brain fart!!

As extra insurance, be sure to put a worm/screw clamp on those push on fittings. I know of two guys who have had the lines come off of the fittings (I have no idea whether they knew what they were doing while they assembled them).

[Chris Sawatsky]

aeroquip very strictly recommends against putting on hose clamps

I've been running the blue hose system without clamps for a few years now with no trouble

[Greg Gauper]

Ditto on the blue hose! Talk about no brainer assembly (or hose assembly for dummies).

One assembly tip I learned....soak the ends of the hose in hot water for about 30-60 seconds before you press the fittings on. The heat helps to soften the hose and makes it easier to slide the fitting on, especially 90 deg. elbows.

Oh sure, now you tell me that!!

A good vise is key as well.

I'm one of the people Scott referred to as having a failure. I could have said that I had used push on hose for a few years now without problems too - until *this* year.

Second use of hose end, new hose, assembled per mfr's instructions. 250 lb. rated hose, blew off at 110 PSI oil pressure going down the front straight at Memphis. I put hose clamps on to get through the weekend, and have since switched to socket hose.

That was Earl's Super Stock hose. Don't know what the problem was - I guess the only solution is to do what they say, but no one does - pressure test after assembly.

My failure may have been a fluke, but I'm not taking anymore chances.

Good luck,
Steven
