SS316 Stainless Steel Gland
The SS316 stainless steel cable gland provides secure mechanical cable entry, environmental sealing, and electrical grounding for industrial enclosures. Manufactured from marine-grade 316 stainless steel, it delivers superior resistance to pitting, chlorides, and harsh chemical washdowns. Engineered for critical applications requiring high mechanical stress tolerance and long-term ingress protection up to IP68 and IP69K.
SS316 Stainless Steel Cable Gland | Marine Grade IP68/IP69K Strain Relief Connector
The SS316 stainless steel cable gland provides secure mechanical cable entry, environmental sealing, and electrical grounding for industrial enclosures. Manufactured from marine-grade 316 stainless steel, it delivers superior resistance to pitting, chlorides, and harsh chemical washdowns. Engineered for critical applications requiring high mechanical stress tolerance and long-term ingress protection up to IP68 and IP69K.
Key Features
Material Integrity: Precision-machined from solid AISI 316 (1.4401) stainless steel, offering high resistance to marine atmospheres, acids, and saline washdowns.
Sealing Structure: Multi-element assembly featuring an EPDM or Viton sealing ring and claw mechanism that ensures uniform radial compression around the cable jacket.
Clamping Mechanism: Polyamide (PA6) or stainless steel claw design provides high tensile strain relief, preventing cable pull-out under severe vibration.
Ingress Protection: Maintains a continuous IP68 (10 bar / 30 min) and IP69K rating when correctly installed, protecting internal electronics from moisture, dust, and high-pressure steam cleaning.

Frequently Asked Questions
Q: How does SS316 differ from SS304 in cable gland applications?
A: SS316 contains molybdenum (2–3%), providing significantly higher resistance to chlorides, marine atmospheres, and acidic cleaning chemicals compared to SS304.
Q: Are locknuts and O-rings included with the cable glands?
A: Yes, every standard gland is supplied pre-assembled with an O-ring (on the connecting thread) and a matching stainless steel locknut.
Q: What is the recommended mounting hole tolerance?
A: Clearance holes should be drilled 0.2 mm to 0.4 mm larger than the nominal major diameter of the external thread.
Q: Can these glands be used for EMC shielded cables?
A: Yes, optional EMC insert configurations with spring contacts are available for continuous 360-degree screen grounding.
Q: What is the minimum order quantity (MOQ) for custom thread sizes?
A: Standard stock items have no strict MOQ. Custom CNC machined threads or special dimensions typically require an MOQ of 500 to 1,000 pieces per size.
Q: What is the standard production lead time?
A: Standard metric and NPT sizes ship within 3 to 7 business days. Custom orders require 15 to 25 business days depending on machine scheduling.
