Sediment Bowl Outlet Threads 2
Posted: Wed Nov 10, 2021 4:32 pm
I have had such poor luck with aftermarket sediment bowls that I decided to buy an original one off Ebay just to clean up and have around for future use. I already had a thread on this topic with another original sediment bowl. In that case, the outer threads were too worn down to engage with the gas line fitting. Bob McCarty recommended an Edelman 168540 fitting and JB Weld and that worked great.
On this sediment bowl, I once again have a problem with the outlet threads. The odd thing is, the outside 2 1/2 threads are in great shape but not at 90° so my fitting loosely threaded in is going in at a angle. But, after the first 2 1/2 threads the internal threads look to be at 90° to the outside surface.
The hole is not elongated or distorted as if someone used force on the fitting to remove the sediment bowl housing. It seems to make sense that someone ran a tap in at an angle cutting new threads but there is no sign of cross threading.
I don’t do helicoils. I realize that is probably the best way to fix it. I think I’ll buy the same Edelman fitting and repeat what I did before but I’m not sure, based on the very good and deep, but askew, outer threads it’ll engage the internal threads and straighten out. Probably my best approach, after I get the Edelman fitting, is to carefully take the peaks off the outer threads so it’ll engage the inner threads and secure it with JB Weld.
I’m just curious if anyone has seen this on a sediment bowl. The threads from top to bottom are in great shape with no sign or cross threading or distortion. It’s like It doesn’t appear to be cross threaded but the angle they were cut changes half way down. I don’t know how you’d create this if you tried.
It’s hard to get a good picture but here’s the best I can do.
