Fermtech Regular Auto Siphon with Tubing, Clear Review (2026)

What comes in this listing

This is Fermtech's Regular Auto Siphon, a 24 inch clear plastic racking cane with a 5/16 inch inlet, and this particular listing pairs it with 8 feet of clear tubing so it is ready to use out of the package. That is worth noting because Fermtech's base auto siphon is sold separately from tubing on the brand's own site, so buyers comparing listings should check whether tubing is included before assuming a price difference reflects a lower quality part. The clear plastic body is a deliberate design choice, since it lets a brewer see the liquid moving through the siphon and tubing and quickly spot air bubbles or sediment being pulled up.

How an auto siphon works

An auto siphon avoids the need to suck on a tube or lift a full fermenter above the receiving vessel, which is the traditional way to start a gravity siphon. Instead, the brewer inserts the outer tube into the fermenter and pumps the inner tube a few times to prime the siphon and start the flow. Fermtech states this design can empty a standard 6 gallon carboy in around 3 minutes once the siphon is running, and the racking cane tip is shaped to draw liquid from just above the trub layer, which helps leave sediment behind in the fermenter rather than pulling it into the bottling bucket or wine carboy.

Materials and durability

Fermtech describes the Regular Auto Siphon as made from a shatter-resistant plastic that the brand positions as more durable than some competing siphons, and the unit is made in Canada. Being a mechanical pump-style tool, the auto siphon relies on a plunger and seal to create suction, and like any seal, that part is a wear item that can lose its grip over years of repeated use, especially if it is not rinsed and dried between uses. The siphon disassembles for cleaning, which helps extend its working life and keeps sanitizer or cleaning solution from being trapped inside the tube where it could contaminate the next batch.

Fit for beer and wine racking

At 24 inches, the Regular size is built for standard 5 to 6.5 gallon carboys and buckets rather than very tall or very short vessels, and the 5/16 inch tubing size is a common standard that fits most bottling wands, spigots, and clamps sold for homebrewing. Because Fermtech is a well established name specifically in auto siphons, this is a reasonably safe choice for anyone racking beer, wine, mead, or cider off sediment for the first time, or replacing an older or cracked siphon. The included 8 feet of tubing is generous for most single-vessel to single-vessel transfers, including racking into a bottling bucket set on the floor below a raised fermenter.

Who should buy this

This siphon suits home brewers and winemakers who want a ready-to-use racking setup without separately sourcing tubing, and who are working with standard 5 to 6.5 gallon fermenters. It is a strong pick for beginners since it removes guesswork around tubing length and diameter compatibility, and the clear body makes it easier to see and understand how a properly primed siphon should look and behave while it runs. Brewers who already own compatible tubing, or who need a longer or shorter cane for a different sized vessel, might get better value from Fermtech's bare siphon or one of its other length options instead of paying for tubing they will not use.
