Stainless steel quick-connect sockets from Water Cannon are precision machined and will resist plug deformation when pressure spikes occur. The flow-through design provides a free-flowing unrestricted bore with minimum pressure loss. The sockets also feature a safety-locking collar with alignment pin; push-and-snap-lock, smooth-action collar with easy-to-grip barreled rings; and a replaceable O-ring for a watertight seal. Rated to 210 degrees F and up to 6,300 psi, they are suitable for heavy-duty use. 800/333-9274; www.watercannon.com
