TruDesign Intake Strainer – Composite Scoop & Round Thru Hull Strainer

Protect your engine and onboard water systems with the TruDesign Intake Strainer—a high-performance composite thru-hull strainer designed to prevent debris from entering your plumbing system.

Manufactured in New Zealand from glass-reinforced nylon composite, this intake strainer offers outstanding strength, durability, and corrosion resistance, eliminating the electrolysis issues commonly associated with metal fittings.

Available in both scoop and round designs, the TruDesign intake strainer suits a wide range of applications:

• Scoop strainers are designed for vessels underway, actively deflecting debris like seaweed and rubbish away from the intake.
• Round strainers are ideal for stationary applications where passive protection is required.

Acting as a coarse first-stage filter, the strainer helps prevent blockages in pumps, filters, and cooling systems, improving reliability and reducing maintenance requirements.

Built to withstand harsh marine environments, TruDesign strainers are resistant to fuel, chemicals, UV exposure, and antifouling coatings, and can be painted or faired into the hull without risk of corrosion or degradation.
