The Prevost PS1 Truflate Safety Coupler eliminates the risk of hose-whip, an issue causing personal injury or vehicle damage. The PS1 vents pressure and then releases the plug with the push of a button. The PS1 uses Prevost long-life seals to produce easy-to-use, leak-free and energy-saving connections. The PS1 Truflate-Profile Coupler features an ergonomic shape and intuitive, color-coded design. The body is made of a lightweight, rugged composite that resists scratching, impact, abrasion, corrosion and is anti-static.
