Many divers credit Halcyon's streamline P-valve as being among their best equipment purchases; the enhanced comfort and peace of mind redefine one’s diving experience.

P-Valves and Catheters


Halcyon Streamlined P-Valve

Whether you are interested in a short, comfortable dive or face long decompression obligations, the Halcyon Balanced Streamline P-valve can provide a new level of diving comfort. Sleek design eliminates bulky connections. Valves chosen to provide minimal backpressure, increasing comfort for female and male divers. 

Add Quick Disconnect

OMS P-valve

The OMS P valve is designed to have the balance valve removed and replaced with a waterproof and pressure proof blank. This also allows the diver to clean and rebuild the valve when necessary but still keep the dry suit in service. Multiple cam features keep the valve from accidently being removed when the diver manipulates the “on-off knob” during the dive.

Add Quick Disconnect

Add Quick Disconnect

P-Valve Quick Disconnect

Robust P-Valve Quick Disconnector with metal clasp. What differs this Quick Release Hose Connector from others is that it is a quick disconnect system with a one-way flow.

As soon as the system is separated the check valve engages and prevents any flow back. Ideal for longer days, boat trips etc. where the P-valve (and catheter) can be disengaged multiple times or divers can attach themselves to the P-valve hose easily.


Rochester Wide Band Catheter

Essential part of a scuba diving pee-valve system. Designed to stay on, the Rochester Wide Band Catheter features 70% greater adhesive area than traditional self-adhering catheters and can be used under any conditions. Made of clear, soft, breathable silicone. Perfect for standard connections as well as the popular one-way P-Valve Quick Disconnect which allows the valve to be disconnected when not in use.

She-P Silicone

The She-P makes it possible for female divers to comfortably use a P-valve while diving in a drysuit instead of using diapers. A soft silicone device featuring a reservoir with ‘output’ tube, that has flexible ‘wings’ that are designed to be adhered to the skin with a medical adhesive. This results in a proper seal and comfortable urinating.
