Hopefully that's just the tank line. If so, no issue with pressure really. Still, cheapo schedule 40 fittings don't shock me if they leak.black iron pipe fittings that are rated for probably 1/20th of the pressure you splitter produces
Would be nice, but its not. ITs a work portHopefully that's just the tank line. If so, no issue with pressure really. Still, cheapo schedule 40 fittings don't shock me if they leak.
Well, you were right on.Most napa and oriley stores make hydraulic hoses so they would have some steel fittings and adapters.
Yea, iron fittings ARE avaliable that go up to 3000+psi, but they are huge, heavy, and expensive. Not what you want or need.
If local sources fail you, online stores like discounthydraulichose.com can hook you up.
Steel fittings will look more like that NPT to JIC 90° adapter you got connecting to that steel tube.
Assume those are 1/2" NPT fittings??? Then these two fittings would replace the black pipe I see

But go through the system. Replace any more you find on there with exeption of the suction and return. Those can be low pressure fittings.
This is the difference between just a "mechanic" working on something, or someone that actually knows about hydraulics. Because someone qualified to do the work the first time around, would have never used teflon tape and black pipe. And I'd never let that person touch another thing of mine that involved hydraulics
Tapered threads seal by metal to metal contact which requires some deformation of the mating surfaces. Using Teflon tape can help when making up tapered thread joints because it acts as a lubricant. So as the joint is tightened and the thread deforms to make the seal the metal has a lower tendency to tear. If the metal tears then it probably won't seal.Have a friend with an excavator that had a real PITA leak on a fitting on the boom. His mechanic wouldn’t use tape. I looked at it and it was a tapered thread. I put teflon tape on it. The leak stopped dry. I think stopping the PITA leak on one fitting with tape is probably “OK”.
I probably should have peeled away the visible tape.
Teflon tape is meant to be a lubricant, not a sealant. It can seal, especially against low pressure, but is really a lubricant. On the other hand, thread sealants do just that, seal.
Bad tapered threads are from poor quality control and from manufacturers that don't care. Tapered threads that are cut using a tap or die are subjected to very high tool pressures which can lead to torn threads. When the tap or die gets dull then tearing is even more likely. Black iron pipe is generally made of a steel alloy that is prone to tearing. Black iron pipe is also a very common pipe for gas plumbing. Go figure. And even though teflon tape may flow into voids under sufficient pressure and hence seal the joint it is not meant to seal and should not be counted on to seal. Best practice is to use the proper thread sealant. The stuff is widely available, cheap, and works very well.Very high pressure flows teflon tape into the voids, sealing the leak path (hopefully).
It's the same goal of any thread sealant.
And it lubricates too thus the joint may be a little tighter.
Teflon tape has a significant risk of "improper application" and can cause problems by contaminating systems.
Bad tapered threads are probably from worn out thread taps & poor quality control.
