What are these hydraulic fittings called

[buddy933]

I've only done two so far. I'm still waiting for a new 14mm die set. The replacements they sent were the 16mm dies. So, the 14mm set I have is unusable. That's the set that would be used most for 1/4" hose and hose ends. They sent me a whole new set of 14mm, but they haven't arrived yet. Hopefully, they should be here in another week.

I've spent the time modifying mine to use an air over hydraulic pump and fine tuning the micrometer and light switch. I also put rubber feet on the bottom. It's just the way I like it now. Just need my dies. I bought a worktable for it but had to send that back. Two of the lower adjustable legs were missing and didn't want to wait two weeks or more for replacements. Home Depot had a sale on toolboxes, so I got their 9-drawer. It's the same as Harbor Freight's except this one has quiet closing drawers and an outlet.

looks pretty good. I have a Kioti DK55, Belarus 611 both with front end loaders buckets and grappler, New Holland DC 75 dozer and a Kobelco SK65, plus a log splitter, so quiet a bet of hoses.

The key on the back of one of the 14mm dies was not centered (see image). This made the whole set unusable. They sent me two replacements but those were 16mm dies. I'm now waiting for a complete new 14mm set. If this turns out to be a bust, I'll machine down one of the 10mm dies to be a 14mm and leave my scathing review.

The radius on the crimp side is about 7mm. The dies are pretty hard, but I've got a 1/2" round-nose carbide end mill that should come pretty close.

someone sure missed that on QC imspection. Was all 8 like that? Hope you get them soon.

No, it was just one, but you can't use it or the rest without one die. The dies are pie shaped so they come together when crimping. The offset key would cause one side to contact the adjacent die before the crimp is complete. It would probably break the keys off or break the press. The press segments that hold the dies float on a tapered piston.

How about BSPP. If you are sealing on the o-ring you don't want a tapered pipe thread.

Our local Rent-All store makes up Hyd hoses to order. They also rent a lot of heavy machinery that requires new hoses, so it's logical.
Beware_ some of the Chinese hoses sold on the web might not meet the specs your machine requires.

I've been buying the Vevor brand hose. I have 1/4, 3/8 and 1/2". It has very good specs. I used the 1/4" hose on the hose press and ran it to over 5,000psi. That's 25% of the burst rating. I plan to use it on my air over hydraulic pump as well.

What you have to watch is the inside diameter of hose fittings. Many of the "brand-name" fittings are custom sizes for their custom hose. It's a scam. The type of hose also matters (R1, R2, R7, etc.). You need to know the outside diameter of your hose as well as the inside diameter of the fittings you buy. Don't buy either of them if the specs aren't provided or don't come close to fitting (.001-.002"). The crimp size can be determined by the formula provided in a previous post above--You can't use the "brand-name" charts for crimping unless you're using their materials.
