MJS(15A~600A) / MJL(20A~600A)
With the rubber gasket inside, the Slip Type (flexible type) Coupling absorbs impact, vibration, bending(2~5°), noise(60% less than welding method), and expansion. Detubulation may happen due to axial force, so it is recommended to fix pipes on its installation.
MJL is a long size model and 1.6~1.8 times longer than MJS, the standard size model.
- Length 300㎜ and 400㎜ are producible for over ND 200A (manufacture by order)
- Use MJD and MJDL (Slip Type - Multi Locks) for over ND 600A
- For higher pressure, choose MJSF and MJSFL (Slip Force type)
Materials:
- Casing: SUS 304 / 316
- Slide: SUS 304 / 316
- Bolt: SUS 304 /316, SS41C, SCM435
