Special Features
Special Features
Griplock is available ‘Loose / Floppy’, ‘Stiff / Stayput’ up to 76mm ID. If it is not required to be especially floppy or stayput the tubing is supplied with Medium Flexibility (Mid Flex) as standard. All sizes over 76mm ID will be supplied mid-flex. Please state the flexibility required in the notes section when placing your order.
Flow Direction
Our Griplock tubing provides a smooth surface particularly in one direction due to the design of its section. We recommend that our customers ensure that the media flow through our tubing follows the Flow Direction of the Hose. There are many benefits to this including protection of the media and tube in addition to ensuring Optimum Flow Characteristics. In addition, it helps prevent damage to the media or tube when used in conjunction with abrasive materials such as plastic pellets.
Flexibility
Griplock is available ‘Loose / Floppy’, ‘Stiff / Stayput’ up to 76mm ID. If it is not required to be especially floppy or stayput the tubing is supplied with Medium Flexibility (Mid Flex) as standard. All sizes over 76mm ID will be supplied mid-flex. Please state the flexibility required in the notes section when placing your order.
Stiff
By ‘squashing’ the tube during manufacture it creates a stiff product tube with increased air tightness & ‘stayput’ properties
Midflex
Our standard product is manufactured ‘midflex’ which is most popular and is ideal for most applications.
Floppy
By loosening the pressure on the tools during manufacture we produce a tube with maximum flexibility that moves freely.
