What Is A Stainless Steel Spiral Flexible Cable Gland?
A stainless steel spiral flexible cable gland, also known as stainless steel strain relief cable gland, is a cable securing and cable sealing connector developed by adding a spiral guard or anti-bending protective spring to a standard stainless steel cable gland; essentially, it is a three-in-one product combining waterproof sealing, cable securing, and anti-bend protection. Compared to standard cable glands, its primary advantage lies in the use of the spiral guard to disperse bending stress, thereby preventing core breakage and sheath rupture at the cable exit point.
1. Product Structure & Materials
Typical stainless steel spiral flexible cable gland includes:
- Locknut: AISI 304, AISI 316, or AISI 316L Stainless Steel
- Sealing ring: NBR, EPDM, Silicone, or FKM/FPM
- Main body: AISI 304, AISI 316, or AISI 316L Stainless Steel
- Clamping insert: UL-Polyamide 6, 94V-2.
- O-ring: NBR, EPDM, Silicone, or FKM/FPM
- Nut with spiral guard: AISI 304, AISI 316, or AISI 316L Stainless Steel
