Advantages
•Can be used both for suction and delivery
Because of the excellent moulding technique combined with tough chemical fibres it may be used at a bursting
pressure of over 850 p.s.i. and within a normal internal pressure of 225 p.s.i. In addition, since it can satisfacto
rily withstand the force for creating a vacuum it may be used on both the delivery and the suction sides. Also, si
nce its carcass is of special spherical type, and it will not come in contact with the connecting bolt head even if
it expands, this connector may be used with a sense of security even when subjectedto high pressures.
•Easy installation on pipeline
Since its carcass is soft and can be readily deformed, pipe connections can be quickly and readily completed
despite some misalignment.
•Excellent ability to isolate sound and vibration
The highly soft carcass isolates vibration and solid sound in all directions and prevents the production of noise
