Item Description

This updated model of the 360 Siphon® helps you avoid as much roof sealant rework as possible, ensuring the installation process is a smooth and easy one.

The 360 Siphon® RV holding tank vent cap eliminates odors from the source — the holding tanks — and exhausts them out the roof vent before they have a chance to invade the RV living space. By design, the patented 360 Siphon can only create an updraft, expelling odors and fostering an oxygen-rich environment to speed up waste breakdown. Breathe easier and enjoy a healthy, odor-free living environment with the 360 Siphon.
