In hazardous and space-restricted industrial environments, cable routing must meet strict safety, performance, and compliance standards. The 90° ADP cable gland adapter plays a critical role in ensuring secure cable entry, explosion-proof integrity, and optimal bending radius where straight cable access is not feasible.
Widely used across oil & gas, chemical processing, marine, pharmaceutical, and power plants, this adapter enables safe right-angle cable entry without compromising enclosure sealing or certification. This guide explains everything you need to know—from selection and sizing to certifications and installation best practices.
What is a 90° ADP Cable Gland Adapter?
A 90° ADP cable gland adapter is a precision-engineered right-angle accessory used with adapter cable glands to redirect cable entry by 90 degrees. It is specifically designed for hazardous area and explosion-proof installations where space constraints, mechanical protection, or cable routing efficiency are critical.
Key Functional Advantages
Maintains IP66/IP68 sealing
Preserves explosion-proof integrity
Reduces mechanical stress on cables
Enables compact and clean cable management
Compatible with armoured and unarmoured cables
Unlike consumer adapters such as HDMI 90 degree adapters, 90 degree USB adapters, or 90 degree AUX adapters, industrial ADP adapters are engineered to withstand extreme temperatures, corrosive atmospheres, and high-risk zones.
Types of 90° ADP Cable Gland Adapters
Designed for Zone 1 & Zone 2 hazardous areas, ensuring flame-path integrity and pressure resistance.
Ideal for outdoor installations requiring dust-tight and water-resistant sealing.
Allows size transition between different entry threads and gland sizes.
Supports pressure equalisation while preventing moisture ingress—often combined with cable gland breather stopper adapter reducer chart selections.

Size Chart & Selection Chart
| Entry Thread | Exit Thread | Compatible Cable Gland Size | Material Options | Hazardous Rating |
|---|---|---|---|---|
| M20 | M20 | 8–13 mm | Brass / SS316 | Ex d / Ex e |
| M25 | M20 | 13–18 mm | Brass / SS316 | Ex d |
| M32 | M25 | 18–25 mm | Aluminium | Ex e |
| PG21 | PG16 | 10–14 mm | Brass | IP68 |
| NPT 3/4” | NPT 1/2” | 12–20 mm | SS316 | Explosion Proof |
Always refer to the adapter reducer chart to ensure correct thread compatibility and certification continuity.
Accessories Used with 90° ADP Cable Gland Adapter
Adapter cable gland
Cable gland reducer
Breather drain adapter
Stopping plugs
Thread sealing washers
Locknuts
O-rings for IP sealing
These accessories ensure a complete cable entry system that remains compliant in hazardous installations.
Connector Compatibility
The 90° ADP cable gland adapter integrates seamlessly with:
Armoured cable glands
Unarmoured cable glands
Barrier glands
Flameproof enclosures
Junction boxes and control panels
Unlike electronic connectors such as HDMI 90 degree adapter, 90 degree USB adapter, or 90 degree aux adapter, this industrial adapter focuses on mechanical protection, environmental sealing, and regulatory compliance rather than signal transmission.
Installation & Maintenance Guidelines
-
Ensure correct thread engagement
-
Apply certified thread sealant
-
Maintain required torque values
-
Verify flame-path clearances
-
Ensure proper cable bending radius
-
Periodic inspection for corrosion
-
Check gasket and O-ring integrity
-
Re-torque during scheduled shutdowns
-
Replace components showing wear
Proper installation significantly extends service life and preserves hazardous area certifications.
Certifications & Compliance
A high-quality 90° ADP cable gland adapter typically complies with:
ATEX
IECEx
IP66 / IP68
RoHS
IS / EN standards
Certification continuity is essential—using non-certified adapters in hazardous areas can invalidate the entire enclosure approval.
