Safety Valve

Safety Valve

  • One-way valve. Our uniquely designed Safety Valve is a one-way valve which attaches directly to the valve stem. It allows air freely into the tire but does not let more air flow out than you need to get an accurate reading from a tire gauge.

  • The discharge flow rate will make a typical 110 psi (7.8 bar) truck tire (315/80/22.5) deflate 10 psi (0.7 bar) in approximately 15 minutes. That is a flow rate of approximately 2.16 cubic inch/sec (35 cm³/sec)

  • Unscrewing the safety valve. In case of the highly unlikely event that a hose is cut or damaged, the safety valve gives the driver enough time to disconnect the damaged hose and unscrew the safety valve while losing only a few psi in the process. He can then top off the air in the tire if needed, and then continue safely on his journey.

 

Hoses

  • The air hoses we use are specially made for the TyreAid at our own factory.

  • We are using a stainless steel braded Teflon hose.  The burst pressure for the hose is 2600 psi (180 bar). Therefore, the hose will not burst from any situation related to tire pressure.

  • The hose couplings on each end are specially designed for the TyreAid. We are using a hybrid design of a JIC/ JIS and Boss connector. The primary sealing surface is a brass against brass application so that over-tightening cannot occur. We also use an o-ring squeezed by a conical shape to make the secondary sealing surface.

  • All hoses require the use of the safety valve. All hose ends and nipples have special threads not found on any common hose. Safety is our priority, so we designed the hoses such that they cannot be attached to a valve stem without the use of the safety valve. Additionally, the hose cannot be replaced by lesser quality common air hoses.

  • All couplings are chrome-plated brass. The couplings are designed to exceed the pressure ratings of the hoses.
