Our tube double couplers are produced here in Australian. They're made from quality stainless steel 304 and can easily withstand the flaring process and withhold its wall thickness. They're designed to joint 2 pieces of straight exhaust tube together without welding. They come in 2 lengths which are 4" or 100mmm which does up to 3" 76mm in size and 3 1/2" 89mm up is 6" or 150mm long. Once installed you will need to use 2 clamps one on either side to tighten the coupler into place. Please check out our store for suitable clamps to complete the job.

Q - What grades of stainless steel do you stock?
A - We offer 3x different grades of stainless steel. Our straight tube comes in 304 or 316 stainless. Our stainless steam straight pipe is a 304 grade.
Stainless steel mandrel bends come in 201, 304 & 316 stainless (different sizes and angles available depending on the grade), our catalytic converters are in a 409 stainless steel.

 

Q - What is the difference between TUBE and PIPE?
A - The difference between tube and pipe lies in the way it is measured. Pipe uses a nominal bore measurement, which utilises the inside diametre as well as the schedule (wall thickness). Tube is measured OD - outside diametre.

 

Q - What is the best material to use for turbo manifolds?
A - When fabricating turbo manifolds, steam pipe has a thicker wall that allows it to cope with the extreme heat exposure. We offer a range of steam products - mild and stainless bends as well as straight pipe lengths.

 

Q - What does CLR stand for?
A - Centre Line Radius is the distance from the center of curvature to the centerline (axis) of the pipe, expressed as a number multiplied by the pipe or tube size. 

 

Q - Can you use petrol cats (catalytic converters) on diesel engines?
A - The cells of catalytic converters have a washcoated surface that makes them unsuitable for use in diesel engines.


Q - What are your size and angle ranges in mandrel bends?
A - We stock a large range of mandrel bends to suit most applications, including car, boat, bike, food grade or for commercial applications.

Bends are available in 3 types of material - mild steel, stainless steel and aluminium.

Stainless steel bends start as small as 1" and go through to 4" - mild steel bends start in 1 1/4" and go up to 4", and alloy bends start at 2" and go to 3 1/2".

Angle ranges vary depending on the material, our mild steel bends have the largest angle range available: 25, 30, 45, 60, 75, 90,125 & 180deg bends in most sizes (from 3.5" up we have just 45 & 90deg bends).

Our stainless steel comes in a 'long leg' and 'short leg' option depending on the grade of stainless you're after. Our long leg bends have much the same range of angles available as the mild steel bends offer. The short leg bends are sold in 45, 90 & some in 180deg.
