Gland Flat Washers Selection Guide: Technical Criteria & Application Standards
Gland Flat Washers selection guide: technical parameters, mounting and compliance standards, and Ortaç comparison.
A gland flat washer is a flat gasket that is fitted on the threaded neck of the cable gland and forms a flat sealing surface between the gland body and the enclosure surface. It is used in sheet metal, plastic or cast enclosures to prevent dust and water from seeping in through the surface the gland sits on and to protect the surface during tightening. In this group, Ortaç washers are available in metric gland sizes such as M 12, M 20, M 32 and M 50 and PG gland sizes such as PG 7, PG 13.5, PG 21 and PG 48. Choose the washer by the thread type and size of the gland, by whether its inner diameter fits the thread and its outer diameter fits the seating surface of the gland, and by the resistance of its material to the ambient temperature. A flat washer is not a metal washer placed under a bolt, nor is it considered the same part as a round cross-section O-ring; which one is suitable is determined by the seating surface of the gland and the manufacturer data. The Gland Flat Washers category on Welibaba includes 20 active models from leading manufacturers such as Ortaç.
Key Technical Parameters for Selecting Gland Flat Washers
To specify the right Gland Flat Washers model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| Cable Gland Thread Type | M12, M16, M20, M25 | Verify against project schedule and load calculation |
| Material | TPV | 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 Gland Accessories.
- 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 Blind Plugs, Gland Gaskets, Gland O-Ring Gaskets.
