Upstream Flow

Industry Proven Sealing Technology

Downstream Flow

Enhanced Reliability Donaldson pioneered RadialSeal™ sealing technology for air filtration more than 20 years ago. We’ve applied this proven design to hydraulic filtration in order to create a clean, leak-resistant seal – with no metal-to- metal contact for a new standard in system cleanliness.

This improved sealing technique protects systems from harmful ingressed contaminants and also prevents cross contamination of oil. By moving the threads outward, the RadialSeal interface increases the surface area which provides a robust connection with superior vibration resistance, a common challenge in today’s heavy-duty applications. RadialSeal™ Guarantees a Reliable, Sure-Fit Robust seal on the clean side of filter is easy-to-torque and provides error-proof filter servicing. No metal-to-metal contact on both the downstream and upstream sides means no cross contamination of oil.

Industry Shaping Media Technology

Synteq XP™ Media Technology for Optimal Filtration Performance Donaldson’s breakthrough in synthetic filter media technology takes hydraulic filtration performance to a whole new level. This resin-free bonded media provides improved filtration to increase filter dirt holding capacity and reduce pressure drop, resulting in enhanced system performance and protection.

Synteq XP™ Media Synteq XP is thermally bonded together to create small, consistent fibers – increasing the filter capacity. The pores remain unobstructed, resulting in reduced pressure drop and more surface area for capturing and retaining smaller particles. Synteq XP Delivers: • Lower operating pressure drop • Higher efficiency for optimal hydraulic system protection • Superior cold-start filtration • Extended filter life (up to 2 to 3 times that of traditional media)
