Guys,

Can you help me...have been trawling the net to buy 2no stainless steel planking plugs for the trumpet inlet base...but can't find a supplier. Standard units are steel 5/8"x1/2".

Any/all help greatly received.

Thanks, Andrew

I would probably think twice about putting stainless plugs in the aluminum base

I always use a decent thread sealer where bolts go into ally threads anyway.

Mike , that's irrelevant.

All metals corrode/oxidize to some point. The main issue when using stainless steel [st/st] fasteners with an alloy is galling when tightening. The heat generated between the two metals causes their base state at the threads surface to change, with st/st surface now being prone to rusting. This is easily overcome by using an appropriate lubricant when tightening i.e copper grease or a loctite depending upon use of the fastener [set screw/bolt]. And to tighten the fastener slowly :. reducing both heat and friction.

Factory standard is a steel plug which is far worse than st/st. Brass/brass alloy plugs are often used which work well with alloys. Again a lubricant should be used.

So back to the original question. Anyone know of a UK supplier who sells these plugs in st/st?

Hi Andrew,
A company that makes just about any sized hose you require must also have adapters e.t.c

Have a look here, earls.co.uk the`re at Silverstone and all good quality I`ve found.

Any hydraulic supplier should carry those in various materials.

Thanks John, I would agree but none of the hydraulic suppliers have them in 5/8". Even my local Co', Unimaster, have no 5/8" plugs in st/st.

The search continues...

Can't you just use stainless button head bolt, loads on google.

Guessing it's UNF? Here's a steel one.

Thanks Tom, no, I want a proper seal provided by a copper washer behind the plug head. So the search continues...
