Stainless Steel Strain Relief Gland
The Stainless Steel Strain Relief Cable Gland (spiral cable gland) provides secure cable entry, environmental sealing, and mechanical bending protection for industrial enclosures and mobile equipment. Featuring an integrated helical spring guard, it evenly distributes bending stress to prevent sharp cable kinks and core fatigue under continuous motion or vibration. Machined from solid AISI 304 or 316L stainless steel, this gland withstands aggressive washdowns, saltwater environments, and chemical exposure.
Product Overview
The Stainless Steel Strain Relief Cable Gland (spiral cable gland) provides secure cable entry, environmental sealing, and mechanical bending protection for industrial enclosures and mobile equipment. Featuring an integrated helical spring guard, it evenly distributes bending stress to prevent sharp cable kinks and core fatigue under continuous motion or vibration. Machined from solid AISI 304 or 316L stainless steel, this gland withstands aggressive washdowns, saltwater environments, and chemical exposure.
Key Features
Material Grade Options: Solid-machined from AISI 304 (EN 1.4301) for standard industrial corrosion resistance or AISI 316L (EN 1.4404) for marine and chemical processing applications.
Helical Spring Guard: Extended stainless steel spiral protects flexible cables from over-bending and mechanical wear at the enclosure entry point.
IP68 / IP69K Sealing: Internal NBR/EPDM multi-layer insert and O-ring deliver dust-tight and high-pressure liquid immersion protection up to 10 bar.
High Pull-Out Resistance: Internal polyamide or metal clamping claw grips the cable jacket securely, offering high tensile strain relief without conductor crushing.

Frequently Asked Questions
Q: What is the primary difference between AISI 304 and AISI 316L for cable glands?
A: AISI 304 suits general industrial environments. AISI 316L contains molybdenum for superior resistance to chlorides, marine salt spray, and aggressive chemical washdowns.
Q: How do I match the correct thread size to my enclosure?
A: Verify your panel knockout or tapped hole against our thread designation chart (e.g., M20x1.5 or NPT 1/2). Metric and PG use parallel threads, while NPT uses tapered threads.
Q: Can these glands accommodate various cable outer diameters?
A: Each model covers a specific clamping span (e.g., 6 mm to 12 mm). Selecting a cable outside this range invalidates the IP68 seal and strain relief rating.
Q: Are locknuts supplied with the glands?
A: Standard packaging includes the gland body, clamping insert, seal, and washer. Matching stainless steel locknuts can be included as an assembled set upon request.
Q: What is the minimum order quantity (MOQ) for custom threads?
A: Standard catalog items have no strict MOQ. Custom thread specifications or specialized body dimensions typically require a minimum batch of 500 to 1,000 pieces.
Q: What is the standard production and shipping lead time?
A: Standard stocked items ship within 3 to 5 business days. Custom production orders require 15 to 25 business days depending on volume and material availability.
