3psi one way check valve

$29.99

Running an open system without pressure and losing coolant?

Well slip this in the overflow tube and voilà; you have mild pressure to keep the fluid in your system.

In an non pressure system the fluid evacuates due to:

excess coolant
thermal expansion
excessive flow from higher speeds
blocked and clogged tubes
water pump impeller design flaws

This handy dandy little check valve will not suck back but it is a great tool for keeping the fluid in for longer.

We make to order. Please allow adequate time for us to build.

Build time estimates [Feb 2025]

Brass/Black Model Ts

Our longstanding foundry (supplier) closed and all production was shifted to a neighboring foundry. Apparently many of the closed foundry's workers were ineligible for rehire by the new foundry due to more aggressive immigration enforcement and the union has no employees to provide. As of 2-20-25, we should receive castings in March 2025 and can resume production then.

In the interim, we have been working with our one-off foundry to have pattern boxes made and these are trickling in in smaller batches and we will produce what we can.

Model As 5-6 weeks

Heater cores ~6 weeks

Model A and 32 Ford Street rods 6 weeks

Common street rods ~12-15 weeks

Tricky customs & complicated restorations ~16 weeks months

We appreciate your patience as we continue to recruit and train new fabricators and manage the labor shortfall our country has been experiencing.
