Pipe fittings for my exhaust

[Chris Lingwood]

I'm having terrible trouble finding and adapter to bring my exhaust back together.

 

I've got some

• flexible exhaust pipe 1 3/8" (35mm) ID
  
• silencer with 1 1/2" bsp male
  
• exhaust manifold with 1 1/2" bst female
  

I can't find anyone who will sell me something which will connect these together with one step.

 

2* 1 1/2inch female bsp 1 3/8 (35mm) hose

1* 1 1/2inch male bsp 1 3/8 (35mm) hose

 

Where oh where can I get them, the swindleries won't even swindle me for one! Plumbers merchants look at me like I'm a retard. God forbid they should pause from selling their new bathroom suites and actually lower themselves to selling some plumbing!

 

If anyone suggests using some different pipe I'll whack them over the head with it!

halfords jubblie clips and exhaust compond any good to you

Get one made in an engineering shop

[Chris Lingwood]

That's exactly how I'm going to attach the flexible exhaust pipe to the hose tail (although perhaps exhaust clamps). But that's no good without the adapters as the 1 1/2inch is markedly bigger than 1 3/8 inch.

 

I want this but with a 35mm hose not 38 damnable mm

Chris, it begs the question, why not change the system now rather than have the problem in the future?

I don't know where you are but if you are close to an industrial area you should find specialist stockists.. The best stuff is steam pipe, all heavy mild steel, they will have flanges which can be readily welded, I wouldn't bother too much with BSP threads and things, weld it up but use flanges where separation is needed. (they will have the gaskets too)

Try ASAP supplies (Google)

 

Edit: Also BES (Google) do a range of stainless conversion fittings.

 

cheers,

Pete.

I think Johns right in using steam barrel for most of the exhaust system. It will last for 50 years.

Find a custom stainless steel exhaust maker in Yellow pages. I struggled for months with a lash up, the local chap made the part in 5 minutes using a thing that looked like an hydraulic dildo. Found this lot on Google, they might help.http://www.turboboost.co.uk/default2.asp?active_page_id=191

hmmm dildos! Sounds......great!

 

ASAP look good but stainless is needlessly expensive which is a shame and the rest is brass. It would cost me abtou £40 to do the converters in stainless.

 

John you are probably right that using steam pipe is best but at least some of it needs to be flexible. There's no way in hell I know how to specify the curve that's on it in such a way as it would ever fit the boat later.

 

I think I've cracked it though. Turns out the outside diameter of 1" bsp is 1 3/8" so I can just convert from 1 1/2" to 1" then clamp on my flexible bit to a barrel nipple. And if I do that I can replace a straight section with proper pipe after I've got it all bolted to the boat. I'll be able to measure it accurately then. What's more is the bits only cost about £8 in total.

 

Welding flanges is all well and good john but the engine manifold has a bsp thread on it as does both ends of my new silencer. Plus I don't know how to weld yet!

 

Chris, it begs the question, why not change the system now rather than have the problem in the future?

 

This is the new one I've ended up with some slightly odd sized pipe because its left overs from someone else's exhaust. BUT it will neatly clamp to the skin fitting. And it is the same as the old stuff. It was just held together with exhaust tape...or not held together. Looked like swiss cheese when I took it apart!
