Interlock Type-A Conduit with Double Wire
Semi-Interlock Double Spring Tube (SAWSP)
Stainless steel wire is inserted into the spiral valley of the Interlock Type A Conduit (Semi-Inter Tube) to create a larger bending radius. Excellent pliability and withstands repeated bending.
Features and Attributes:
- The doubling of the stainless steel wire produces a stable outer diameter. The increased stability results in no elasticity, and can provide optimum protection for optical fibers. Especially for laser fibers, quartz-type optical fibers, hollow optical fibers, etc.
- Stainless steel wire is inserted into the spiral valley of the Interlock Type A Conduit to create a larger bending radius. (Refer to figure 1 in Technical Specs.)
- It is also possible to modify the bending radius by changing the wire diameter and rod.
- Excellent pliability.
- Withstands repeated bending.
- RoHS Compliant
Standard Product:
- Flexible Tube Material: Stainless Steel (SUS304), Aluminum (Optional)
- Spring Material: Stainless Steel (SUS304), Aluminum (Optional)
- Sheathing Variety: Glossy Soft Polyvinyl-Chloride (PVC), Polyethylene (LDPE , HDPE), Polyurethane (TPU), Polyolefin (PO). More options are available, please view Customizations
- Length: Maximum continuous length is 10 meters. However tubes can be joined to make a maximum of 30 meters in length. Please contact us for details.
- All customizations outside of the standard listed above, will be custom and made to order. Please view Customizations for a full listing of available options.
Services Available Upon Request:
- Double Washing: Double washing treatment (using detergent) can be applied to tubes for high precision applications.
- Chemical Polishing: We offer tubes with chemical polishing, which provides extra shine for optical applications. (Special polishing for semiconductor-quality applications also available.)
Common Applications:
- Protection of optical fiber for dental lasers
- Protection of optical fiber for high-power lasers and welding machines
