Pressed swivel couplers are pressing from premier-grade steel plates. Among these, the British standard pressed swivel couplers are pressing from 5mm steel plates. While the Japanese and Korean type pressed swivel couplers are pressing from 3mm steel plates.

British Type Pressed Swivel Coupler

Wellmade British-type pressed swivel couplers are tested according to EN 74 Class A standard. It is used to connect with O.D 48.3mm scaffold tube in 3.2mm lightweight. The technical details and load capacity of the British pressed swivel couplers are as following:

  • Weight: 1.00KG
  • Thickness: 5mm
  • Slipping Force: Required: 10KN, Test Result: 20KN
  • Failure Force: Required: 14KN, Test Result: 23.52KN
  • Size: O.D 48.3mm
  • Finishing: Yellow Passivate

Japanese Type Pressed Swivel Coupler

Wellmade Japanese & Korean standard pressed swivel couplers are also called JIS swivel clamps. It is made from a 3mm steel plate which is lighter than the British standard pressed swivel couplers.  The Japanese pressed swivel clamps are tested according to JIS A 8951 standards. Following are the load capacity and technical details for the JIS standard pressed swivel couplers.

  • Weight: 0.65KG
  • Thickness: 3mm
  • Slippage: Required: Less than 10 mm at 7355N
  • Failure Load: Required More than 10787N, Test Result: 12277N
  • Eye Bolt Nut Forque: 44.13 N.M
  • Finishing: Zinc Plated

Scaffold pressed swivel coupler is a rotation double clamps. It is used to fix two scaffold tubes at any angle. Which is different from the fixed right angle couplers. In construction and engineering, the pressed swivel couplers are used a lot in adding diagonal braces to the scaffold. Include ledger braces, face braces, etc.

Pressed Swivel Coupler Sizes

The most popular pressed swivel coupler sizes are O.D 48.3mm for British standard scaffold tubes and O.D 48.6mm for JIS standard scaffolding pipes. More than the O.D 48mm scaffold tubes, there are also other sizes for the pressed swivel couplers used to connect scaffold tubes to the scaffold props and scaffolding frames.  Include

  • O.D 48.3xO.D 60mm
  • O.D 42.7xO.D 48.6mm
  • O.D 42xO.D 48.3mm

More than the pressed swivel couplers, there are other scaffolding pressed couplers. Include:

Forged Swivel Coupler VS Pressed Swivel Coupler

Both forged swivel couplers and pressed swivel couplers are used to connect scaffold tubes at any angle. The differences are mainly in the fabrication process. Forged swivel couplers are made from steel round bars. The scaffold round bars are heated at high temperatures. Workers forging the round bars to form the forged swivel coupler covers and bases. While the pressed swivel couplers are from pressing not forging.  You can find the pressed swivel couplers covers and bases are pressing by molds and jigs.

In load capacity, the forged swivel couplers are higher loads than the pressed swivel couplers. Thus pressed swivel couplers are always used to connect light scaffolding pipes. Standard light scaffolding pipes thicknesses could be 3.2mm, 3.0mm, 2.4mm, 2.2mm, and 1.8mm, etc.  If you want to fix heavy scaffold tubes, like 4.0mm BS1139 standard, it is better to use the forged swivel couplers.

Both pressed and forged swivel couplers use 8.8 class bolts. In BS1139 standard, the swivel clamp bolts are in 1/2″ with 21mm cross nuts and washers. While in JIS standard, the pressed swivel clamps are assembled by 7/16″ bolts and 17mm flange nuts.

In galvanizing finishing, both forged and pressed steel swivel couplers are able to be zinc plated and hot-dip galvanizing. The galvanizing surface extends the longer life of the swivel clamp scaffolding. While hot-dip galvanizing swivel couplers are the most durable way. It is not only able to use in civil, industrial, and commercial construction but also used in onshore and offshore scaffolding construction like oil and gas scaffolding, petroleum scaffold, shipbuilding construction, etc.

Pressed Dual Swivel Coupler and Half Swivel Coupler
