Goof Plug - Dual End 1/4" & 1/8"

Product Description

Also called a "Mistake Plug", it is used to plug holes in drip poly tubing or cap off 1/4" micro tubing. Large and small plug ends will accommodate both large or small holes. Use the small side to plug the end of 1/4" line or 1/4" holes in 1/2" mainline tubing. If the smaller end of the goof plug does not completely seal the hole, use the large end of the plug for a tighter seal.

Tips & Tricks

Upgrade Your Drip Hole Punch & Save Time

A clean cut makes it easier

Some drip irrigation hole punches are shaped like a pencil and simply poke a hole as they push through the tubing. They require more force and can slip off of the drip tubing before they make the hole. The Super Punch (shown here) has a squeeze handle and is only $9.90. A less expensive option is our Deluxe Hole Punch which has a sharp, circular cutting edge. It's comfotable, easy on your hands, and costs only $3.60.

A Paper Clip Quickly Cleans a Hole Punch

Insert the wire to clear the tool

A good hole punch will actually cut a tiny circle out of the drip tubing. The plug of tubing can be removed from the cutting edge of the punch with a paper clip. Push it through the cutting end to clear any plastic debris.

Fix Little Holes With a Goof Plug

Doubles as a 1/4" end plug

If you make a mistake and poke a hole in the wrong place on a drip line, insert a goof plug (small barb). If the hole gets worn and leaks a little, pull the plug out and use the large barbed end. Goof plus are also used to plug the end of 1/4" micro tubing.

Fix Big Holes With a Coupler

If a goof plug won't do the trick

If you have a hole in a mainline poly pipe that is bigger than a goof plug, a compression coupling is the fitting to use. Make a clean cut and insert the two tubes into each end of the coupler. No glue required.

FAQ

I want to install my own drip irrigation system. Where do I start?

The best place to start is our Drip Irrigation Basics & Installation Tutorial. You'll learn how to plan & design a drip system, connect to a hose bibb, and how to compare drip emitters.

How do I determine my water flow rate?

The flow rate is the amount of water flowing through your water supply line. Since drip emitters and micro sprays consume x gallons per hour, it is important to know the flow rate available to feed your emitters. It is measured in gallons per hour (GPH). To determine the flow rate out of your faucet (hose bibb, spigot, hydrant), read our tutorial on Determing Your Flow Rate.

How do I choose the right drip emitter (dripper)?

Drip Irrigation design is flexible. There is no perfect solution. However, there are a few guidelines to consider when choosing & comparing drip emitters. The first consideration is pressure compensating vs. non pressure compensating emitters. Pressure compensating emitters contain a silicone diaphragm that is designed to keep the flow rate consistent.

A pressure compensating emitter will deliver the stated flow rate (e.g. 2 gallons per hour) within a pressure range. The output of non pressure-compensating emitters will vary as the water pressure varies. If you plan to install the maximum number of emitters a mainline, you should consider pressure compensating emitters so that you don’t run out of water flow. Non pressure compensating emitters are designed to operate at 20 psi or less, so they should be installed with a 20 psi drip regulator.   

Pressure Compensating Emitters

• Deliver the stated gph (gallon per hour) even if pressures range from 10-50 psi
• Works well with elevation changes
• Self-flushing to reduce clogging

 

Non-Pressure Compensating Emitters

• The output will vary with changes in pressure and elevation
• Less expensive than pressure compensating emitters
• Recommended pressure: 15-20 psi

Tutorial: Chosing The Right Drip Emitter

Can I bury my drip tubing?

We do not recommend burying drip tubing in the soil. However, a layer of mulch on top will extend the lifespan of the drip tubing. Buy Drip tubing here.

Goof Plug

Also called mistake plugs, goof plugs are used in drip irrigation to plug up small holes in mainline drip tubing. They are also used as end caps in 1/4" drip micro tubing. It is always good to keep a handful of goof plugs on hand.

See Goof Plug

Micro Tubing

Sometimes called "Spaghetti Tubing", 1/4" micro tubing can be used as main line for small deck/flower-pot installations, but is more often used as a lateral line coming off a 1/2" poly supply line (main line).The micro tubing carries water to emitters (drippers), and micro sprays. Also referred to as "Distribution Tubing" it is available in polyethylene or, the more flexible, vinyl. See also Drip Tubing, Lateral Line, Micro Spray,Micro Sprinkler, Main Line.

Bug Plug

Also called an "Insect Plug", a bug plug is installed in 1/4" drip tubing to keep insects from entering and clogging the tubing. Bug plugs do not restrict the flow of water to plants.

Hole Punch

A device used to poke a hole into solid drip poly tubing for the insertion of drip emitters (drippers). See also Poly Pipe, Emitter.
