How to Install the STX250-475S Cable Fitting
Instructions for installing the STX250-475S Star Teck™ cable fitting with integral seal.
Estimated time: 30m
Tools needed:
Hacksaw, Screwdriver
Supplies needed:
Sealing compound (SC4-KIT-1 or SC65), Fiber damming material
- Prepare the cable jacket and armor
Determine the working length of conductors. Remove a portion of the outer jacket to expose the armor. Cut the armor using a hacksaw, being careful not to nick the conductor insulation. Trim the outer jacket to the strip length indicated in the table.
- Feed cable through gland nut
Feed the cable through the gland nut opening and push until the cable armor hits the end stop.
- Tighten gland nut
Tighten the gland nut until an appropriate seal is obtained or to the maximum torque specified in the table. Ensure the bushing and collar ring seal evenly around the cable's outer jacket and are flush with the gland nut face. Keep the cable centered for an optimal seal.
- Disassemble fitting components
Loosen the union to disassemble the hub from the body sub-assembly. Unscrew the sealing chamber from the body sub-assembly.
- Prepare conductors
Trim the inner jacket to a length of 1/8"-3/8" to expose the conductor bundle. For shielded data cables, remove the outer shield and filler materials, taking care not to damage inner shields.
- Apply sealing compound
Depending on the sealing compound used (SC4-KIT-1 liquid or SC65 putty), follow the specific instructions in Section 3 or Section 4 of the manual. This involves packing fiber damming material, mixing and applying the compound, and ensuring all voids are filled around the conductors. For SC4-KIT-1, larger fittings require a two-stage fill with a waiting period. For SC65, ensure the compound is mixed thoroughly and applied at or above 70°F (21°C).
- Reassemble and mount fitting
Screw the sealing chamber back onto the body sub-assembly until it is completely seated. Mount the hub in the desired location. Once the sealing compound has solidified (approximately 1 hour), place the encapsulated assembly into the hub and secure by tightening the union until metal-to-metal contact is achieved. Remove any excess compound from the outside of the sealing chamber with a damp cloth.
