Tunable Stainless Steel Header Water Pressure T-Valve

The Hardin Marine T-Valve is a spring/ball style water flow check valve designed to control the flow and time of release of the water into water injected exhaust headers thus rendering the headers dryer and hot at an idle when properly adjusted and allow water flow at the appropriately tuned higher engine RPM's.

By adjusting a boats water inlet or exit you can control the water pressure that is feed to the T valve. The unique advantage of the Hardin Marine tee valve is that it features threaded exits ports. This thread allows use of optional brass tuning jets (Sold Separately) for additional control of the amount of water flow you may desire for your particular application.

The optional brass water jets are available with a 0.100 orifice and can be drilled out to allow additional water flow if so desired. This T-Valve accepts 2 brass water jets. The 316L premium grade stainless steel tee valve features -8AN or (3/4X16UNJ thread) connections. Also replaces #BR-TVALVE-73.

Restrict your water flow as necessary with these Restrictors (Sold Separately). NO LONGER will you need to drill and tap fittings for water restriction!

Replacement Header Lines for Most Water Injected Headers

These are replacement water injection lines designed to work as replacements for missing or damaged lines on most water injected header applications on 8 cylinder engines. These kits include easy bend cupronickel tubing with a centrally mounted intake block. Each intake block contains 4 ports for each individual line and a female 1/2" NPT port for water intake from your pressure T-Valve (adapters sold separately). The kit includes 4 short, 4 long lines, 2 intake blocks and 8 fittings for the intake blocks. This will allow for building replacement lines on 2 headers or 1 engine. Header mounted fittings are not included. Please note: This is a do it yourself kit, you will have to bend the tubing to the appropriate shape for your headers. Returns will not be accepted on any kits with bent tubing.
