SEAM commercial diving helmets, a premium option of our commercial dive helmet for sale, ensure safety and performance in underwater welding, salvage, inspection, and construction. Built for harsh marine environments, they offer reliable sealing, durable materials, and clear communication for professional divers, solidifying the reputation of our commercial diving helmet for sale in the industry.
Our diving helmet accessories are compatible with parts from internationally recognized brands.
Choosing the right diving helmet depends on the helmet construction, breathing system, communication interface, working depth and the type of underwater operation. The comparison below provides a practical overview of SEAM's three commercial diving helmets for sale, helping contractors and diving teams identify the model that best matches their equipment configuration and operating requirements.
| Selection Factor | CDM39 | CDM39-Y | TF12 |
| Helmet Construction | Stainless steel shell | Stainless steel shell with carbon fiber coating | Tinned copper shell |
| Air Weight | Approx. 14.10 kg / 32.43 lbs | Approx. 14.10 kg / 32.43 lbs | 18.6 kg |
| Breathing / Air Supply System | 455 balanced regulator; optional 350 regulator | 455 balanced regulator; optional 350 regulator | Surface-supplied, triple-ventilation design |
| Airflow / Safety Control | Balanced demand regulator system | Balanced demand regulator system | One-way check valve rated at 0.05 MPa airtightness for emergency air retention |
| Face Port / Windows | Scratch-resistant polycarbonate face port | Scratch-resistant polycarbonate face port | Tempered-glass faceplate and ear windows with anti-fog design |
| Communication | Quick-change communications module | Quick-change communications module with MarshMarine male 4-pin connector | Integrated diving phone system |
| Side Block / Air Connector | Not specified on the current product page | UNF 9/16"-18 | Not specified on the current product page |
| Neck Seal | Neoprene neck dam | Neoprene neck dam | Reinforced neck ring with leather gasket |
| Published Diving Depth | Not specified on the current product page | Not specified on the current product page | 45 m standard; 60 m maximum allowable |
| Best Selection Consideration | Suitable when a stainless-steel helmet, balanced regulator and modular communication system are preferred | Suitable when the CDM39 breathing platform is required together with a carbon fiber coating and clearly defined communication and side-block interfaces | Consider for surface-supplied operations requiring a ventilated copper helmet, particularly where the published operating-depth specification and integrated communication system are important |
Choose CDM39 when the priority is a stainless-steel helmet with the 455 balanced regulator and a quick-change communication system. Its stainless-steel construction is designed for corrosion resistance and straightforward maintenance in demanding subsea environments.
Choose CDM39-Y when you need the same basic regulator and communication architecture as the CDM39 but prefer a stainless-steel shell with a carbon fiber coating. The published MarshMarine 4-pin communication connector and UNF 9/16"-18 side-block connection also make this model easier to evaluate when matching the helmet with an existing surface-supplied diving system.
Choose TF12 when the project calls for a traditional ventilated copper helmet and the operating-depth requirement needs to be evaluated against a published specification. The TF12 uses a surface-supplied triple-ventilation system, tempered-glass viewing windows, an integrated diving phone and a one-way check valve, with a stated standard diving depth of 45 meters and maximum allowable depth of 60 meters.
Before ordering, confirm the required working depth, breathing-gas supply arrangement, communication connection, umbilical interface and other system compatibility requirements with SEAM so that the helmet configuration can be matched to the intended diving operation.

Our SEAM diving helmets are trusted by professionals for reliability, adaptability, and excellent value in demanding underwater environments.
Our SEAM commercial diving helmet was successfully used in an offshore pipeline inspection and maintenance project in Southeast Asia, a proven application of our commercial dive helmet. The project required long-duration underwater work under strong currents and low visibility. SEAM helmets, a star product of our commercial dive helmet for sale, provided excellent sealing, stable air supply, and clear communication, ensuring diver safety and efficiency. As a reliable piece of commercial diving equipment, the SEAM helmet was also compatible with the client’s existing systems, reducing integration costs. Our fast response and technical support were highly praised by the offshore contractor, further enhancing the appeal of our commercial diving helmet for sale for critical projects.
The SEAM Commercial Dive Helmet is fully certified to meet the rigorous requirements of CE (European Conformity) standards.The helmet provides superior impact protection, corrosion resistance, and respiratory performance for surface-supplied diving operations.
The helmet shell is constructed from a rugged, lightweight glass-reinforced polyester (GRP) or stainless steel material. Other metal components, including the demand valve housing, buckles, and fitting screws, are manufactured from chrome-plated brass or stainless steel to provide maximum resistance to corrosion in saltwater and harsh offshore environments.
Yes, the SEAM helmet features a standard 4-pin underwater communication connector and #6JIC air hose connector that is widely compatible with most industry-standard diver communication boxes and umbilical.
The SEAM helmet features an integrated defogging system that directs a controlled flow of air across the inside of the faceport， ensuring clear vision throughout the dive. No batteries or manual application of defogger solution is required for standard operation.
In the event of an emergency, the helmet is equipped with a quick-release buckle system on the chin strap and a side-mounted swivel latch mechanism. This allows a tendered or the diver themselves to remove the helmet quickly, even while wearing thick gloves. The design ensures the helmet can be detached from the diver in seconds without compromising the neck seal integrity during normal use.
Yes, the SEAM helmet utilizes a sophisticated side-exhaust system. This directs exhalation bubbles away from the faceport and the diver's ears, significantly reducing inhalation noise and bubble interference. This design enhances communication clarity and provides a quieter, more comfortable diving experience compared to front-exhaust models.
The SEAM helmet is designed with modularity in mind. The communication (comms) assembly—including the microphone and headphones—is housed in a user-accessible compartment. This allows for easy maintenance, replacement, or future upgrades to digital communication systems without needing to replace the entire helmet shell.
