Default Brake Junction Block Plug Leaking

Folks, I have R front brakes and some other mods that require plugs in the distribution block. I Googled the part number listed on Dave Barton's site and the first listing was IPD. No surprise, so I bought them, but no matter what I try, they leak under pressure.

In retrospect, I just noticed that the IPD plug has the brand listed as "Aftermarket". Has anyone else used these IPD plugs and had leaks? Do you think ones listed as "Genuine Volvo" will make a difference over the IPD aftermarket plugs? Hate it when nickel & dime items cause such an annoyance.

Tks

How's the block itself look? Perhaps the threads on the junction are damaged?

Gonna be hard to tell with fluid flowing out of it. Is there some type of thread sealant or a plug with a flange and sealant washer?

I used some leftover (caliper) bleeders to plug the unused ports on my distribution block. Works great. If you have some, try them as an experiment. Could be the angle on the aftermarket plugs are different?

"FIXED"

Turns out it was leaking by the sender o-ring and trickling down onto the plugs.
