1/2" Auto-Siphon Clamp

The 1/2" Auto-Siphon Clamp is designed to securely hold a 1/2" auto-siphon in position during beer, wine, and mead transfers. By keeping the siphon upright and elevated above sediment layers, this clamp helps reduce sediment pickup during racking and bottling. Designed for use with large 1/2" auto-siphons, the clamp provides added stability when transferring liquid from buckets, carboys, and other wide-mouth fermentation vessels.

Built for homebrewing and winemaking workflows, the clamp helps simplify hands-free siphon positioning while supporting cleaner liquid transfers between fermenters, bottling buckets, and kegs. Maintaining proper siphon height above trub, lees, or sediment can help improve clarity in finished beverages and reduce unwanted sediment carryover.

The 1/2" Auto-Siphon Clamp is compatible only with large 1/2" diameter auto-siphons. It is not compatible with 5/16" mini auto-siphons or standard 5/16" large auto-siphons. The clamp is intended for use in wide-mouth fermentation vessels such as buckets and larger carboys where stable siphon positioning is important during racking operations.

To use, attach the clamp to the edge of the fermentation vessel and position the auto-siphon securely within the holder. Adjust the siphon height as needed to help avoid disturbing sediment during transfer. Remove and clean after use before storing for future brewing sessions.

Widely used in homebrewing and winemaking setups, the 1/2" Auto-Siphon Clamp provides a reusable solution for improving siphon stability and supporting cleaner beverage transfers during fermentation and bottling.
