The Fully Tested SuperLite® 17B Commercial Diver’s Helmet Set The Working Standard For The Commercial Diving Industry Worldwide...

Many thousands of underwater hours have proved the design to be dependable, comfortable, extremely rugged, and is Commercial Rated™ and CE certified. The SL-17B has been tested and certified to meet or exceed all requirements for all governing agencies. It is certified for use in diving operations world wide.

The helmet system consists of two pieces: the neck dam-yoke and the helmet. The diver slips on the angled neck dam with the attached yoke. The neck clamp is then slipped onto the helmet and locked. The locking system not only seals the neck dam to the helmet but also secures the front of the yoke.

The SuperLite® 17B also includes our Quad-Valve™ Exhaust System which retrofits to many of our Helmets. This exhaust has exceptionally low exhalation resistance that you must experience to appreciate. The new SL-17A/B Helmet Retainer™ (chin strap) along with the new SL-17A/B Yoke Retainer™ (yoke strap) make it virtually impossible to have the hat come loose. These upgrades are standard on all new SL-17B helmets and will retrofit to all previous SL-17 A/B Helmets.

The Side Block Assembly is standard in the B configuration, receiving the umbilical over the shoulder (17B as shown). The SuperLite® 17B offers comprehensive head protection, an adjustable demand breathing system for gas economy, antiflooding features, rapid emplacement, a neck dam clamp that mechanically breaks a low-pressure lock, and a trim to fit angled neck dam which seats the helmet comfortably, especially when working in the face down position. The pull pin neck clamp release provides a system for prevention of accidental helmet removal.

SuperFlow® Regulator - The 505-027 SuperFlow® "B" regulator on the SuperLite® 17B offers high performance. The regulator has been tested at Dive Lab at Panama City, Florida. It meets all current U.S. Navy and European diving standards.
Air Train - The air train diffuses incoming breathing air/gas onto the face port/lens to defog and ventilate.
Brass Handle - Handle can be removed without breaking seals, making it quick and easy to attach accessories.
Chin & Yoke Strap Kit - The SL-17B Helmet ships with a low profile strap system designed to retain the helmet to the neck clamp/yoke assembly in the event these two main components accidentally become separated.
Defogging Steady Flow Valve - Provides an additional flow of gas into the helmet for ventilation and defogging.
Emergency (EGS) Valve - Supplies backup breathing gas to the diver.
Fiberglass and Carbon Fiber Reinforced Shell - Kirby Morgan® has over 50 years experience in composite laminations. The helmet shell is hand laid up glass fiber reinforced thermal setting polyester (fiberglass) with carbon fiber reinforcement at key points for added durability. It is light and highly impact resistant, and provides a heat/cold barrier as well as being an excellent electrical nonconductor.
Gas Supply Non-Return Valve - Commercially Rated™ It prevents loss of gas pressure in the event of umbilical damage.
Nose Block Device - Allows the diver to block the nose to equalize ears.
Side Block - Multi use side block has additional ports built in to provide controlled air flow, if needed.
Silicone Oral Nasal Mask - Made of a superior silicone material which is hypo-allergenic and has a longer work life than latex.
Whisker Wings - Bubble deflecting Whisker wings keep bubbles further from face port and ears, improving visibility and decreasing internal noise.

Weight - 29.03 lbs
Helmet Shell - Fiberglass, polyester resin, polyester gel coat, and carbon fibers
Control Knobs - Polyurethane
Face Port/Lens - Scratch Resistant Polycarbonate

Recommended Lubricants - All helmets and masks are lubricated at the factory with Christo-Lube®. Kirby Morgan recommends Christo-Lube® or Tribolube® for all gas train components. Dow Corning® 111 Silicone or equivalent may be used for helmet and mask components that are used with gas mixtures containing less than 50% oxygen.
Regulator - The 505-027 SuperFlow® regulator on the SuperLite® 17B offers high performance. The regulator has been tested at Dive Lab at Panama City, Florida. It meets all current U.S. Navy and European diving standards.
Operational Specifications - Maximum depth on air 220 FSW (67 MSW) with the old style single exhaust or the Tri-Valve Exhaust®. Maximum depth on air - 150 FSW (45.73 MSW) when equipped with the old style double exhaust whisker assembly. Maximum depth on HEO2 Surface Supplied, 330 FSW (100 MSW) Work rate - Heavy - 62.5 - 75 l.p.m. RMV. Maximum current - 3 knots with standard exhaust, 5 knots with Tri Exhaust Umbilical 3/8” Maximum length 600’ (183 MSW) Breathing Gas Requirements, 4.5 a.c.f.m. at the side block at depth.
Cage Code - The cage code for identifying KMDSI products for U.S. government purposes is 58366.
CR Standards - These helmets meet or exceed all standards established by Dive Lab of Panama City, Florida, and are CR (Commercially Rated) marked.
Temperature Limitations - Use at water temperatures below 33 °F (1 °C) requires use of hot water shroud (P/N DSI 525-100) and hot water.

The Hot Water Shroud (Part# DSI 525-100) in conjunction with hot water to the diver should be used whenever diving operations are conducted using HeO2 at water temperatures less than 60°F (15.56°C) for the comfort of the diver. KMDSI further recommends that the shroud be used in conjunction with hot water to the diver whenever diving operations are conducted using air or mixed gas, in waters colder than 36°F (2.22°C) to reduce the possibility of demand regulator icing. 

Usually the greatest danger of demand regulator icing will be encountered on deck when the surrounding air temperature is less than 32°F (0°C). This effect is primarily due to the refrigeration effect of breathing air pressure reduction, and the addition of moisture from the diver's exhalation coming in contact with the topside air temperature. 

If diving where the water temperature is 36°F (2.22°C) or warmer but the topside air temperature is below freezing, (32°F (0°C) icing of the demand regulator is possible. To help eliminate the possibility of freezing on the surface, warm water should be run over the exterior of the demand regulator prior to water entry, if the hot water system is not used. 

The umbilical assembly should be composed of good quality diving hose that meets industry standards. Generally, gas hose will be married to the communications wire, pneumofathometer hose, and strength member in a manner that will allow the strength member to receive all the strain. There are also good quality umbilicals available that are assembled at the factory using a twisted method which does not require marrying. Regardless of the system used, the umbilical is the diver’s life line and should always be of excellent quality and maintained carefully. 

This system has been used successfully for diving in biologically contaminated environments for many years. To further reduce the possibility of water intrusion regardless of the exhaust system being used, the diver should avoid working in an inverted position. 

The Tri-Valve exhaust System has now been replaced by the Quad-Valve System. The unique design of the Quad-Valve keeps exhalation resistance low while maintaining excellent watertight integrity.
