Is this the legit seal that boundary ships with?
If not, what seal is it? I can tell you its as hard AF and feels like a kids toy.

Hmmm. Wonder if my giant oil leak on the front of the motor that I installed yesterday has anything to do with that. If it turns out my leak is from the crank seal I will update.
I would contact Boundary directly. They aren't sponsors here and may not be watching.

Numbers are probably 50,5 for 50.5mm outer diameter. 36.5 for inner diameter.
If someone could measure an OEM seal we could compare.
But its probably the right dimensions. I have an OEM seal at home I can compare to.

The dimensions are right, its just that no one I know recognizes the brand at all and I wonder if this seal 'accidentally' ended up on this pump between leaving boundary and arriving at my shop.

AFAIK boundary does not modify the pumps themselves in any way other than the gears.
For example I just found that my allen plug leaks. Hopefully not my main seal. I'll know more after I let the rtv dry.

Andrew I have purchased a few of these from different vendors, and I cant remember who this one came from. I Just want to know if its an abnormal seal or if we did something wrong during assembly because we have had so many leaks on so many builds.

Afaik Andrew does not change the seals (he will have a real answer though). And I heard from Travis that they haven't changed anything in 15 years. It might just be bad luck.
