AKM 80 Pcs JIC 37° Flare Cap and Plug Kit Industrial Hydraulic Cap and Plug Hose Tube and Pipe Fitting Kit Precision Threading in Dash Sizes 4 6 8 10 12 16

Good quality for the price

The fitting build quality is excellent. Function is as expected. Great value for the price. Fittings are durable enough to be used again and again.I used them to cap lines on my tractor to test blow by on a cylinder. They worked as expected and definitely a great addition to my toolbox.

Never heard of this brand before but they are of good quality. Just as good as what you get up town

Same ones most hydraulic shops sell, way cheap and amazing. Box is kinda cheap but super good deal!

Replacing hydraulic lines or doing cylinder work on equipment really require caps unless you like contaminated systems, seal failure, and a huge mess.This set contains all the common size caps and plugs I would need to maintain a backhoe and bucket. Critically, it comes in a plastic case to keep them organized and (relatively) clean. Putting a gritty plug into an otherwise clean system is not good for the longevity of seals or pump! I checked the threading on some equipment currently being overhauled and both caps and plugs were accurately threaded and fit snugly. Finish seemed good for the pricepoint and I do not foresee rust being a problem.While I have not had to use this set yet this spring in the field, I am sure as the summer progresses that some lines will need some love and I'll update this review.

Caps fit like they should and high quality.

Good quality and well organized.

These work great when working on hydraulic lines and/or capping off lines or outlets. They hold and don’t leak. The kit has all the standard sizes needed.
