KTJ11630 Hydraulic Return Filter
450mm Heavy-Duty Element for Hitachi EX200-5 & John Deere 790E | Replacement for Donaldson P550702, AT127608
Product Summary
The AYREST KTJ11630 is a high-capacity hydraulic return line filter engineered for heavy excavation and construction machinery. Designed specifically to handle high-flow return oil, it features a reinforced full-metal outer shell to prevent element collapse during cold starts or sudden pressure spikes. This filter is a 100% precision-fit alternative to Donaldson P550702, Hitachi L4325820, and JCB 335G0531, maintaining ISO-grade oil cleanliness for sensitive Kawasaki and Rexroth hydraulic pumps.
High-Collapse Strength
Equipped with a 0.8mm thick, corrosion-resistant perforated steel support tube. Unlike budget filters, the KTJ11630 maintains structural integrity even under backpressure exceeding 20 Bar (2.0 MPa).
10-Micron Precision Media
Utilizes premium multi-layer inorganic fiberglass. This ensures a Beta 200 rating, capturing 99.5% of metallic wear particles and contaminants that cause valve sticking.
Industrial-Grade Epoxy
The filter media is bonded to the end caps using high-temperature thermosetting epoxy, ensuring zero bypass leakage at operating temperatures up to 120°C.
