    Loose Pulse nipple cause air leak?

    Would a loose pulse nipple cause an air leak? Is there anything that can be used to re attach pulse nipple such as lactate red?

    Yes it will cause an air leak. Green loctite will probably work better than red, but I doubt either will last very long. Best bet would be to tap it and install a barbed fitting

    Thanks for the advice. I ordered some new brass nipples, thinking maybe that might be an easy fix as the old one might have deformed over the years being pulled out a few times. If that doesn't work, I'll definitely tap and install a new fitting as you describe.

    The fittings not threaded... Tap it in means press fit. I would also ruffen up the top surfaces of the cases and after tapping the fitting in build up a boss with JB weld.

    Oops, I misread that as drill and tap the hole and install a threaded fitting. Luckily I didn't do that. I'll tap(press) in the new brass nipple when it arrives tomorrow. One question, when you say build up a "boss" with JB weld? Do you mean I should build up a bit of a dam, in a cone shape on the top surface of the case where it meets the nipple?

    Jb weld them in. Of course after you clean the surfaces up really nice.

    New brass nipple on the pulse line definitely fixed the air leak. Thanks.

    I've seen that several times. Clean thoroughly with carb cleaner and a q-tip. Then add a bit of red loc-tite and tap back in using an aluminum or brass drift.
