Brass Swivel Spiral Fittings Selection Guide: Technical Criteria & Application Standards
Brass Swivel Spiral Fittings selection guide: technical parameters, mounting and compliance standards, and Ortaç comparison.
A brass rotating spiral conduit fitting is a brass connector that connects galvanized and PVC-coated galvanized spiral conduit to an enclosure or device entry, and whose threaded part rotates independently of the body holding the conduit. Because the thread turns separately, the conduit can be screwed into the entry without twisting; it is used in motor, sensor and machine-mounted junction boxes and on lines where the conduit is fixed beforehand. In this category, the Ortaç MDP series is listed with codes corresponding to PG thread sizes such as 7, 9, 11, 13.5, 16, 21 and 29. Choose the PG size of the fitting according to the thread at the entry and the conduit side according to the inner and outer diameter of the spiral conduit; confirm from the manufacturer data the protection rating suited to the humidity and dust conditions of the environment. On plastic spiral conduits, polyamide snap-in fittings are used instead of these fittings. This series is not the same product as the external-type brass fitting made for heavy-duty (liquid tight) spiral conduits. The Brass Swivel Spiral Fittings category on Welibaba includes 10 active models from leading manufacturers such as Ortaç.
Key Technical Parameters for Selecting Brass Swivel Spiral Fittings
To specify the right Brass Swivel 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 Fixed Spiral Fittings.
