O-ring face seals, often used on John Deere......who sells a cost effective kit of plastic or at least low pressure , cheap caps and plugs to retain oil and keep contamination out while fittings are disconnected? Thanks again.
i bought a set from cat for like $30 it has tons of plastic blue caps/ plugs of all sizes and it comes in handy. theyre all organized into different slots by size and are numbered so you can put them back where they belong when your done using them.
http://www.caplugs.com/Hydraulics/ They have an online store too. Edit: It looks like you have to buy a minimum of 1000 of each size - not good. After a quick google search, this came up: http://www.winzerusa.com/?__event=browse_catalog&pid=4d890707dcb2f7c33eb65101
Take a look at discount hydraulics. They have good prices on steel caps and plugs. Lawson sells a kit with the plastic or they can make you one up of the size you need.
i recommend the same kit eric12 is talking about from the cat dealer. in 2008 my kit was $56, in 2011 it was $64. without a doubt the least i have paid for this quantity of parts from my cat dealer!! they come in a two sided plano tackle boxes.................theironoracle
