They are used for the purpose of joining two ø48 mm. And ø60 mm. outside diameter tubes at various angles. Produced in steel forging quality. (They are also produced in metal sheet quality but they are not preferred by manufacturers that produces the high quality products)
They are produced by connecting two single couplers (which are custom produced with the holes on the joint points) and one swivel pin, formed from total 11 parts. 4 main parts which will grip two pipes from all around, 2 pins which attach two parts, 1 pin which makes two parts movable, 2 t bolts, 2 nuts.
Just like one chain is as strong as its weakest ring, couplers also gain durability and function in direct proportion with the strength of its constituent parts.
For this reason in coulers different bolts and nuts are used. Complies with en-74 requirements for Europe in the production. T bolts are replaceable.
T bolt quality is generally 5.6 but it may be done 8.8 by choice. It provides maximum reliability with its high durability and long lasting enduring.
The spanner which will be used for screwing the nut is no: 21 for the set up of the product.
It is electro galvanised against the corrosion risk which would lower the performance.
It complies with welding process because it is a drop forged product.
Ribs which grips the surface prevent the slipping of the tubes.
