The Parker PT Series Low Pressure Return Line Filters provide an economical alternative for quality tank top mounted filtration. With a Parker space saving design that protects the quality of filtration, the PT Series offers both modularity and value.

The Parker PT Series is available in two diameters and three lengths, with flow capacities up to 50GPM/188LPM depending on viscosity. The PT2 and PT4 filter cartridge models utilize Microglass III media in 2, 5, 10 and 20 microns for the industry’s best particle removal efficiency and retention. This return line filter applies In-to-Out Filtration, ensuring that any captured contamination is retained in the element during servicing the filter, preventing system recontamination.

The unique design simply threads into a ported weld or flange. The PT element can be integrated directly into a co-polymer reservoir. (Note: Parker Filtration can provide cavity details to co-polymer reservoir manufacturers for support of this innovative solution). The direct screw-in design creates a compact, flat reservoir surface, which typically reduces the first fit cost. Compared to the traditional tank top mounted filter, improved sealing between the reservoir and the filter can be achieved, eliminating potential leakage areas. Because all seals are pre-mounting, this reduces the risk of replacing the incorrect seals, assuring safety. This compact solution is ideal for supporting mobile applications.

The PT Series features a disposable filter cartridge, a single-piece construction, incorporating both the nylon cover and the bypass valve, located in the end cap. The cavity also includes the integrated return line port and optional connection for the pressure switch. The flow path is inside-out and requires no special tools for service. This design assures minimal installation costs with the least space requirements for return line applications.
