Ubrew USA Auto-Siphon Regular with 6.5 Feet of 5/16" Tubing and Clamp Review (2026)

Who this siphon fits

This kit pairs a Fermtech Regular auto siphon with 6.5 feet of 5/16 inch food grade tubing and a clamp, packaged and sold by Ubrew USA. It suits home brewers who are assembling their first racking setup and do not already own compatible tubing, since it removes the need for a separate tubing purchase before the first transfer. The Regular size bore fits standard homebrew carboys, better bottles and fermenting buckets, making it a good general purpose choice rather than one built specifically for oversized vessels. Anyone moving up from siphoning by mouth, or replacing a cracked plastic racking cane, will find this a sensible, fuss-free starting point since the siphon, tubing and clamp all arrive matched and ready to sanitize.

Size, materials and design in plain English

The auto siphon itself is Fermtech's Regular model, built around a 5/16 inch racking tube, which is the more common bore size for standard five gallon homebrew batches. The kit includes 6.5 feet of clear, food grade tubing made in Canada, which is enough length to comfortably reach from a fermenter on a table or counter down into a bottling bucket or carboy on the floor. A clamp is also included, which attaches to the vessel to hold the siphon cane in place so it does not slip down into the sediment layer at the bottom during a transfer. Like other auto siphons, it starts with a single pump stroke rather than requiring you to draw liquid up by mouth.

Living with the siphon day to day

On transfer day, the clamp attaches to the rim of the carboy, bucket or jug, holding the siphon cane steady so you can pump the center tube to start the flow without the cane drifting toward the trub or sediment. The clear tubing lets you watch the liquid as it moves, which is useful for spotting when you are getting close to the sediment layer and should stop the transfer. Because the tubing is 6.5 feet long, it comfortably reaches between a raised fermenter and a bottling bucket sitting on the floor. After each use, both the siphon and the length of tubing need thorough rinsing and drying, since residue left in the tubing over time can build up and is harder to fully flush than a plastic siphon body alone.

Trade-offs and how it compares

Against the Fermtech Fast Flow Large 27 inch siphon with its 1/2 inch bore, this Regular kit moves liquid more slowly during a transfer, but it fits standard carboy necks without the fitting issues a wider bore can run into. Compared with the Fermtech Regular 5/16 Auto-Siphon sold without tubing, this Ubrew USA kit's main advantage is that it bundles tubing and a clamp together, saving a separate purchase for anyone building a first setup. The trade-off against a large-bore siphon is transfer speed, since the narrower 5/16 inch tube means longer racking times on full five gallon batches compared with the Large model's wider bore.

Verdict and who should pick something else

This kit suits beginner to intermediate home brewers who need a complete first-time racking setup, including tubing and a clamp, and who are working with standard size carboys, better bottles or buckets. It is a sensible, no extra purchases needed starting point. Brewers who already own compatible tubing and just need the siphon itself may prefer a standalone Fermtech Regular siphon at a lower cost. Anyone racking large batches frequently and looking to cut transfer time and oxygen exposure should instead consider a large-bore siphon like the Fermtech Fast Flow Large, accepting that its wider cane may need more care fitting into narrow carboy necks.
