Blu-Sub Deep-Sea Cable Penetrators are engineered to seal tightly around matching subsea cables. A compatibility guide is included above, listing specific Blu-Sub Deep-Sea cable types alongside the recommended penetrator sizes for proper fit. These penetrators are also compatible with other deep-sea cables from different manufacturers — refer to the specifications for guidance, and feel free to contact us to confirm compatibility.
Alternative Cable Penetrator Options
Blu-Sub offers a range of cable penetrators to meet different installation methods, enclosure types, and underwater depth requirements:
Deep-Sea M10 Gland Cable Penetrators – Threaded M10 design with a compression gland for removable, modular sealing. Ideal for deepwater enclosures requiring strain relief. Depth Rating: Up to 1,000 m / 3,281 ft
Low-Depth M10 Gland Cable Penetrators – A compact and cost-effective solution for shallow water and low-pressure systems. Depth Rating: Up to 100 m / 328 ft
Mid-Depth M8 Gland Cable Penetrators – Slim-profile gland suitable for tight mounting areas or small form-factor enclosures. Depth Rating: Up to 300 m / 984 ft
Compatible With: Blu-Sub Enclosures & Mounting Interfaces

Subsea Aluminum End-Cap
Select models feature pre-drilled ports or blank positions that can be tapped or drilled to accommodate various penetrator thread sizes (e.g., M6, M8, M10).
Subsea Acrylic End-Cap
Available with precision-machined thru-hole patterns to support multiple penetrator sizes (e.g., M6, M8, M10). Designed for use with rear locking nuts and intended for shallow-water applications where internal visibility is required.
Subsea Polymer Flange & End-Cap
Can be easily user-drilled to support different Blu-Sub penetrator sizes, making it ideal for custom shallow-water assemblies.
Subsea Watertight Enclosure Box
Includes 20 pre-drilled M10 ports for fast integration of cable penetrators, connectors, and sensors in a sealed box configuration.
Subsea M10 Coupling Tube
Designed for in-line cable splicing and external mounting of penetrator-based devices such as signal indicators, sensors, or switches. One end features a single M10 threaded port, with the interior cavity used for sealing and strain relief.
Compatible Installation Tool
Sold Separately
This product can be installed using the Universal M8/M10 Installation Wrench, a dedicated tool designed for Blu-Sub M8 and M10 bulkhead-style components such as penetrators, switches, sensors, and connector-style hardware.
Its compact dual-end design allows installation in tight or closely spaced layouts, while cable-pass slots allow the wrench to slide over pre-attached cables, enabling installation or servicing without disconnecting wiring.
Compatible Shielded Cable Option
Sold Separately
For subsea systems that require both power conductors and protected data conductors, the Deep-Sea Shielded Data & Power Cable is available as a hybrid underwater cable option with shielded twisted-pair data conductors.
This cable may be used with compatible sizes of the Deep-Sea Cable Penetrator for potted cable pass-throughs into watertight enclosures, end-caps, or subsea housings. Final waterproofing and depth performance depend on cable preparation, potting method, installation quality, and the lowest-rated component in the finished assembly.
Refer to the cable compatibility guide when selecting the correct penetrator size for each cable type.

What type of sealing material is recommended?
For strong, permanent seals, use epoxy resin such as Loctite Epoxy Marine. For non-load-bearing or removable installations, sulfur-based adhesives like 3M2131 are also suitable.
How do I install or remove the cable penetrator?
Use a wrench on the flat sides of the bulkhead for proper torque. If the workspace is tight, you can use snap ring pliers to engage the semi-circular groove at the head for positioning or adjustment.
Do I need to apply thread locker?
Applying Loctite thread locker between the nut and the bulkhead is recommended to prevent loosening. Be careful not to let thread glue contact the O-ring or sealing surface.
