Engine manufacturers are using Parker check valves as fuel pressure regulators in their trucks. In other words, they aren't just controlling the direction that fuel is flowing but controlling the amount of fuel delivered to the engine. Check valves acting as fuel pressure regulators have been helpful to OEMs attempting to meet Tier 4 compliance. Tier 4 is the most recent engine emissions standard implemented by the Environmental Protection Agency.

Swivel fittings are designed to eliminate hose twist and torque that may contribute to premature hose failure. Available in 90 degree and in-line styles with a wide variety of port ends, Parker swivels are ideal for an array of dynamic applications. Swivel fittings are made up of a shaft side and housing side, both of which have different ports and configurations to match your system needs.
