Dual-Action Punching and Insertion for Agricultural Systems
The .400 Barb Punch is a highly specialized, commercial-grade tool designed exclusively for large, high-flow .400 barb fittings like the LSB400 Tape Loc x Barb. When laying out extensive agricultural rows or market gardens, punching individual holes and wrestling large barbs into place by hand is an exhausting, time-consuming process. This dual-action tool solves that problem by allowing you to punch the hole and seat the fitting into your 3/4″ mainline tubing simultaneously in less than ten seconds.
Engineered for speed and durability, the tool features an amazingly sharp hardened steel tip molded directly into a solid, ergonomic plastic handle. You simply slide your oversized fitting over the metal shaft, push the tool into the mainline with a slight twist, and pull the tool away. The hole is punched and the fitting is perfectly seated in one smooth motion. A protective plastic cover is included to keep the steel tip sharp and protect the user when stored in a tool bucket.
- Simultaneous Action: Specifically engineered to punch the tubing and insert the fitting in one continuous motion, drastically reducing installation time.
- Oversized Capacity: Creates the exact wide-diameter hole required for large .400 high-flow agricultural fittings.
- Hardened Steel Tip: The ultra-sharp metal tip easily cuts through thick-walled 3/4″ and 1″ mainline tubing without crushing the pipe.
- Protective Cap: Includes a durable plastic cover to shield the sharp tip and prevent dulling when tossed into a toolbox.
- Ergonomic Grip: The solid molded plastic handle gives you excellent leverage to push oversized barbs into stiff tubing.

A quick guide to simultaneously punching and inserting large fittings.
Step 1: Load the Tool
Remove the protective plastic cover. Take your LSB400 fitting and slide it completely over the metal shaft of the punch until it rests against the base of the plastic handle.
Step 2: Position the Punch
Secure your 3/4″ or 1″ poly mainline tubing so it does not roll. Place the exposed hardened steel tip of the punch exactly where you want to start your drip tape row.
Step 3: Push and Twist
Apply firm, downward pressure while giving the handle a slight twist. The sharp tip will easily puncture the mainline tubing wall.
Step 4: Seat the Fitting
Continue pushing downward until the barbed end of your loaded fitting is forced into the freshly cut hole. Once the barb is fully seated, simply pull the tool straight out, leaving the fitting securely locked in the tubing.
