Explosion Proof Brass Gland EExd 501/453 (often listed as Hawke 501/453 series) is a widely used hazardous area cable gland manufactured by Hawke International (now part of Hubbell). It's designed for safe cable termination in explosive atmospheres, commonly in industrial settings like oil & gas, petrochemical plants, refineries, and other Zone-classified hazardous locations (common in regions like the Middle East, including Oman).
Key Features and Certifications
- Protection Types: Dual-certified for Ex d (Flameproof/Explosion-proof) and Ex e (Increased Safety), with some variants also supporting Ex nR (Restricted Breathing).
- Hazardous Area Ratings: Suitable for Zone 1/21 and Zone 2/22 (Gas Group II, including IIA, IIB, IIC in many cases), and often Zone 21/22 for dust.
- Certifications: ATEX and IECEx approved (global standards for explosive atmospheres); may include other regional approvals.
- IP Rating: Typically IP66/IP67/IP68 (weatherproof and dust-tight, with deluge protection in many models).
- Cable Types: Primarily for armored cables, including:
- Single wire armour (W),
- Wire braid (X),
- Steel tape armour (Z),
- Elastomer/plastic insulated cables.
- Sealing: Double-seal design (inner and outer seals) for reliable cable retention, inner sheath seal, and armor termination/earthing.
- Material: Standard brass (often nickel-plated for corrosion resistance); alternatives include 316 stainless steel or aluminum.
- Thread Types: Metric (M20, M25, M32, M40, M50, M63, etc.), NPT, or others; "RAC" variants often indicate specific configurations like reduced armor clamping.
- Variants:
- 501/453/UNIV (Universal) — Broad compatibility, including cold flow protection for certain cable types.
- 501/453/RAC — Often with restricted armor clamping or specific adaptations.
Common Sizes and Applications
Popular entry sizes include M20 (e.g., 20mm), M25, and larger. For example:
- A 20mm (M20) version handles smaller armored cables in tight spaces.
- Used for securing and sealing cables entering explosion-proof enclosures (e.g., junction boxes, motors, panels) while maintaining the enclosure's integrity.
