Newb ?: Sealing fuel pressure regulators for chromate plating?
Posted by admin on April 5th, 2009 at 12:16am
I have two engine’s worth of Bosch fuel pressure regulators that I want to have re-plated (yellow zinc chromate) by a local plating company . I have them bead blasted but am stuck on how best to seal the fuel line connections, as I’d imagine the rubber diaphragm inside would not appreciate the plating proces….The problem is the connections are M16 x 1.5 threads. One possibility is this:
If I seal the threads with PFTE tape, would that be an adequate seal to submerge these?
I also sent away to a plastics company for some samples of threaded plastic caps that you see on pipes to protect the threads. I got the sample yesterday and they’re a perfect fit but I don’t know whether the plastic seals the threads tight enough, or whether the plastic would survive the plating process.
I know I should just go ask the guy at the plating shop, but that’s a 40 mile round trip. Thoughts? Thanks!
