  • $37.99

This is the Duotight BlowTie 2 Diaphragm Spunding Valve With Gauge Kit, your ultimate solution for pressure control in gas and liquid lines. Crafted with high-quality non-corrosive acetyl, nitrile, and stainless components, this spunding valve ensures durability and reliability.

Designed for easy installation, the spunding valve features two mounting points at its base, allowing secure attachment wherever you desire. It serves a crucial purpose: reducing the pressure in your gas or liquid lines. Whether you need to lower the CO2 pressure going into a keg or regulate the main water pressure within the range of 0-15 PSI, this valve has got you covered. The included gauge, suitable for pressures up to 15 PSI (or up to 100 PSI with different gauges), provides clear and accurate readings.

Unlike poppet style spunding valves, the diaphragm design of this valve offers enhanced accuracy and control. By utilizing a larger surface area on the diaphragm, adjustments to the pressure are smoother and more precise. This ensures that the remaining pressure after gas release closely matches your desired blow-off pressure.

With Duotight fittings, installation is a breeze. Simply push in the compatible tubing, and the dual EPDM O-rings inside each fitting provide superior sealing capacity. The straight cut of the tubing guarantees a complete seal and optimal performance.
