Product Information
The Bare Si Tech Valve Port is a polyurethane mounting base that is glued or welded to the inside of a drysuit, creating a watertight socket into which a SI TECH inflation or exhaust valve threads. It has a 70 mm outer diameter and a 33 mm inner diameter, and it fits all SI TECH valves.
Who it is for
This accessory is for drysuit owners and drysuit service techs who need to install, replace, or service a SI TECH inflation or exhaust valve. Because the valve threads into the port rather than being permanently bonded to the suit, the valve itself can be removed for maintenance without disturbing the watertight attachment to the suit.

Frequently Asked Questions
What does a SI TECH valve port do on a drysuit?
It is a polyurethane base that is glued or welded to the inside of a drysuit, giving SI TECH inflation or exhaust valves a threaded, watertight socket. The valve screws into the port, so the valve can be removed for service without breaking the watertight bond between the port and the suit fabric.
Can I install the Si Tech valve port myself?
SI TECH recommends that attachment be performed by a professional drysuit service facility rather than by the diver, since the port must be glued or welded to the inside of the suit to form a reliable watertight seal.
Will this valve port work with any SI TECH valve?
Yes. The port is designed to fit all SI TECH inflation and exhaust valves, so it works on either the inlet or exhaust side of the drysuit as long as a SI TECH valve is being used.
What are the dimensions of the Si Tech valve port?
The port has a 70 mm outer diameter and a 33 mm inner diameter, and it is made of polyurethane (PU). These dimensions are set by the manufacturer, SI TECH, under item number 60852-CUT.
