Tax included.

Keep your TruDesign vented loop working perfectly with the TruDesign Vented Loop Spare Parts Kit—a replacement duckbill valve, cap, and cleaning pin, designed for use with 19 mm, 25 mm, and 38 mm loops. Simple to install and essential for maintenance, this kit ensures your vent continues to prevent siphoning in san­i­ta­tion systems, holding tanks, and engine cooling lines.

Made from the same durable glass-reinforced nylon composite as the loop itself, the spare parts maintain high strength, corrosion resistance, and dimensional stability—just like the originals 

Key Features:

  • Complete service kit: duckbill valve, cap, and cleaning pin

  • Compatible with TruDesign loops in 19 mm, 25 mm, and 38 mm sizes 

  • Restores proper siphon relief and sealing performance 

  • Same composite durability as original loop—ideal for harsh marine environments 

Easy Maintenance Tip: Remove the cap, clean the duckbill valve and vent port, inspect for damage, and replace promptly if worn .
