OX Pro Heavy Duty Sealant Gun 400ml

Product Information

This caulking gun doesn’t have a plunger. Instead, it pressurizes the space behind the caulk to push it through the tube, allowing for consistent pressure. It comes with a regulator to adjust the pressure for optimal flow as well. Standard design and lightweight yet sturdy construction have made this gun the industry standard for many years.

First, we really liked that this electric caulk gun utilizes the same battery lineup that many DIYers already own. Next, we like that it produces even and consistent results without wearing out our hands. We also enjoyed the worklight and swiveling frame, as well as the adjustable speeds. We realize that it’s expensive, but anyone applying construction adhesive to floor joists will find that this caulking gun pays for itself in a day or two. We found the easiest caulking gun to use during testing was the Newborn 250 caulking gun. It had plenty of power, a comfortable grip, a swivel frame, and dripped less than most other models on the list. Q. Can I use caulk without a caulking gun? Testing the PC Products steel caulking gun was enjoyable. It had plenty of thrust for squeezing out sealant despite below-freezing temperatures. We liked that the frame revolves as well. While it does have a smart puncture wire storage (it’s spring-loaded behind the trigger), it doesn’t feature a cutter, which could be a downside for some.Next, we tested each with an acrylic caulk to see how smooth, consistent, and easy they were to work with. We caulked a seam between two boards and then allowed the guns to rest to see how much they’d drip. Repeatedly squeezing a trigger can lead to hand and wrist fatigue, which is why powered caulking guns are becoming more popular. When they first hit the market a few years ago, powered caulking guns were reserved for commercial and industrial projects. Today, DIYers are discovering the benefit of letting the gun dispense the sealant so they can focus on creating a smooth bead. With no hand trigger, thrust ratio does not apply. Instead, dispensing pressure is regulated via a light squeeze on the finger trigger. Testing the best caulking guns was pretty straightforward: load them up, test their power, see if they drip, and compare the results. But there was one twist: It was pretty cold in our shop. Temperatures were just under freezing when we tested the caulking guns, which meant we were really putting them through the ringer. This caulking gun features a 10:1 thrust ratio and easily dispenses light to light-medium viscosity caulk, making it well suited for latex and silicone. This gun’s smooth-pull hand trigger and dripless technology are a plus, and so is the fact that it comes with a built-in seal puncturing tool, a cutting tool, and a handy hook for hanging the gun on a ladder rung.

In some areas, the Red Devil was excellent during testing. The rubber grip was comfortable yet grippy, and there was plenty of power for squeezing out caulk or sealant in cold temperatures. Unfortunately, it did drip during testing, and the frame didn’t swivel smoothly, but we felt its sturdy build quality and power warranted a spot on the list. With its revolving frame, the Newborn 250 makes it easier to caulk around corners. No need to start and stop—simply rotate the barrel, and the angled tip of the tube rotates to the correct position to continue running a bead.

There were quite a few things to like about the Newborn 188 during testing. For one, we appreciated the sturdy welded construction, as it felt like a quality piece despite its reasonable price tag. We also liked the built-in cutter and puncture tool, as they make getting to work faster and easier. The one downside we found was that this caulking gun was more difficult to squeeze than others.
