4″ to 2″ 99.9% Copper Tri Clover Bowl Reducer with 1/2″ BSPP Front Port

This high-quality bowl-style reducer is crafted from 99.9% pure copper, providing excellent thermal and catalytic properties ideal for distillation. It features a Tri Clover (Tri Clamp) connection, reducing from 4″ to 2″, and includes a 1/2″ BSPP (British Standard Parallel Pipe) threaded port on the front face.

Key Features:

• Material: 99.9% Copper – enhances sulfur compound removal during distillation.

• Connections:

  • Top: 4″ Tri Clover (TC)

  • Bottom: 2″ Tri Clover (TC)

• Front Port: 1/2″ BSPP threaded fitting – compatible with standard 3″ dial thermometers

• Design Purpose: Optimized for mounting on the top of a 4″ still column or gin caddy.

• Safety Upgrade: Specifically engineered to accommodate analog 3″ dial thermometers. The previous digital thermometer port has been replaced to comply with updated safety guidance — digital probes are now discouraged due to ethanol vapor ignition risks.

Use Case:

Ideal for distillers seeking a safe and accurate way to monitor head temperatures during spirit runs or botanical infusions. The integrated threaded port ensures a secure thermometer fit without compromising vapor path integrity.
