Press-Fit Nipple (10 Pack)

Follow these simple steps to assemble your fogger head.

Step 1: Connect to the Fogger
Push one end of the press-fit nipple firmly into the base inlet of the 4-Way Fogger (MF4W) until it seats completely.

Step 2: Attach the Barb
Take the opposite exposed end of the nipple and press it firmly into the smooth top opening of your Press-Fit Barb (MEBARB).

Step 3: Insert into Tubing
Use a punch tool to create a clean hole in your poly mainline tubing, then snap the barbed end of the fully assembled fogger unit into the hole.

What is the Press-Fit Nipple used for?
This press-fit nipple directly connects a 4-Way Fogger to a Press-Fit Barb, allowing you to easily install the fogging assembly into your polyethylene mainline tubing.

It acts as the essential bridge piece, converting the smooth base of the fogger into a barbed fitting ready for insertion.

Do I need glue to install the Press-Fit Nipple?
No glue or special tools are required. The press-fit nipple uses a simple friction fit to securely attach the fogger to the barb without leaking.

Just apply firm pressure to push the components together.

Does the Press-Fit Nipple plug directly into poly tubing?
No, this nipple does not plug directly into the tubing. You must attach it to a Press-Fit Barb first, which then punches securely into the mainline.

Attempting to push the smooth nipple into a punched hole will result in leaks and blowouts.

Are Press-Fit Nipples reusable?
Yes, they can be carefully pulled apart and reused. However, repeated removals may weaken the friction grip over time, so permanent placement is generally recommended.

If the connection feels loose after multiple uses, it is best to replace the nipple to prevent leaks.

How do Press-Fit Nipples help prepare my greenhouse for the upcoming summer heat?
Press-Fit Nipples allow you to rapidly assemble and deploy 4-Way Fogger systems. As late spring temperatures rise in May, these leak-free connections ensure your greenhouse cooling system operates reliably, preventing heat stress on vulnerable plants.

Because early summer heatwaves can quickly cause temperature spikes inside a greenhouse, ensuring your misting system is fully operational is critical. The friction-fit design of these nipples allows you to quickly replace broken heads or expand your cooling zones before the intense summer sun arrives.
