Brass Fixed Spiral Fittings Selection Guide: Technical Criteria & Application Standards
Brass Fixed Spiral Fittings selection guide: technical parameters, mounting and compliance standards, and Ortaç comparison.
A brass fixed spiral conduit fitting is a brass fitting, with body and thread in one piece, that is fitted to the end of metal spiral conduit and connected to a hole in enclosure sheet metal or to a threaded entry. It is used at enclosure, junction box and machine housing entries for galvanized and PVC-coated galvanized spiral conduits, in fixed installations where the conduit can be turned freely before connection. In this category, the Ortaç MPR series is available with PG size codes such as 7, 9, 11, 13.5, 16, 21, 36 and 48. Choose the fitting accordingly by determining the PG thread size at the entry, the nominal diameter of the spiral conduit and whether the conduit can be turned during installation. For connections that will be screwed in after the conduit has been fixed, the rotating type allows more practical installation. A spiral conduit fitting is not a cable gland: it holds the conduit, not the cable, and does not provide sealing on the cable sheath. The Brass Fixed Spiral Fittings category on Welibaba includes 10 active models from leading manufacturers such as Ortaç.
Key Technical Parameters for Selecting Brass Fixed Spiral Fittings
To specify the right Brass Fixed Spiral Fittings model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Wrench Size | 15 mm, 17 mm, 20 mm, 22 mm | Verify against project schedule and load calculation |
| Connection Thread | PG (DIN 40430) | Verify against project schedule and load calculation |
| Thread Length | 10 mm, 12 mm, 14 mm, 8 mm | Verify against project schedule and load calculation |
| Thread Size | PG 11, PG 13, 5, PG 16 | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in Spiral Conduit Fittings.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as External Brass Swivel Spiral Fittings, External Brass Fixed Spiral Fittings, Brass Swivel Spiral Fittings.
