I bought these to used with a vacume/pressure tester, they do not hold pressure or vacume. I havent tried filling a case with them, but id assume its just going to leak the entire time your filling the case.
These should not leak. We supply them with our pressure/vacuum tester and they provide a consistent seal. If you are leaking between the quick connect fittings, contact customer service and we will replace them.
Non of 3 adapters fit my Yamaha F150 lower unit right out of the box. I had to run a M8x1.25 dye on the tread to make the thread compatible.
The length of the threaded part is longer than both lower unit check and drain screws, so I had to cut out some length to achieve the pressure tight seal.
GREAT GEARCASE ADAPTER GREAT WORKMANSHIP WORKS GREAT WITH MY VAC/PRES TESTER HIGHLY RECOMMEND
Needed these to pressure test my outdrive. Worked awesome, Like all of the other tools I have ordered from Marine Tech.
These adapters work great. Unfortunately, I purchased the gearcase pressure/vacuum testing kit with these adapters included. One of them was defective so I had to purchase this additional kit so I could use the tool I purchased. Customer service was of no help to me.
The adapters are fine as far as function. The knurls on the adapters SUCK! Whoever is making these needs more practice knurling!
Just poor workmanship and quality!
Your hands are going to be oily which is the purpose of the knurls to get a grip.
I will leave this review here even though I certainly disagree with your assessment of 2 star quality of the machining. Maybe the knurls could be a bit deeper for your liking but they are clean and the parts are nicely made. - Leon (owner)
Hello. I stopped by the shop a few weeks back and picked up the gear case adapters brought them to the shop and they love them. Bought a set just for me
