Hydraulic line fitting size?

[traderrik]

I want to connect a pressure gauge into my loader's hydraulic system; would someone happen to know what size male quick-connect fitting I will need? It's an LA854.

Someone posted awhile back that it's an ISO Series 'B' 3/8". But looking on the chart at the link below, the stem size of 3/4" (measurement 'A') seems awfully large. But I'm just going from memory, as my tractor is 150 miles from here.

Quick-Disconnect Couplings

I appreciate any info you may be able to provide!

I have an LA 853 on a Grand L 4330 that I am sure has 3/8" hose. I will measure the couplers when I use it Sunday and let you know.

Thanks, FF - but please don't go to much trouble; I was just hoping someone might know...

On my Kubota L-series the QD's are Parker 60 Series - ISO B. The loader cylinder lines and fittings are 3/8" size. Some of the valve supply, power-beyond, and return hoses are 1/2" on some models but in recent years they are getting smaller - 3/8" is now common for those too. Hope this is what you're after.

rbargeron, that's exactly the info I need. Thanks!

The full ISO number for that coupler is 7241-1 Series B. The 3/8" size usually comes with 3/8" NPT female thread. The link below is a size chart for hydraulic quick couplers. Print it out at full size 100% scale, and hold a male coupler you have up to the profiles. The one that matches your coupler is the one you need.
