OX Pro Heavy Duty Sealant Gun 400ml

Product Information

With a 6:1 thrust ratio, this model is best for dispensing low-viscosity sealant, such as painter’s latex caulk. It comes with a built-in pin for puncturing the seal on the caulk tube and a built-in cutter to nip off the tip of the tube. With zinc-coated corrosion-resistant sliding components, it is the go-to gun for the professional & DIY trades. During testing, we found the Newborn 250 to be the easiest and smoothest for applying caulk and sealant. The frame rotated smoothly (certainly the smoothest of all the other models), and the hand grips were very comfortable. We also liked the built-in cutter that most high-thrust caulking guns don’t have. It did drip a bit, but the release was easy to access and press with one hand. The only complaint we might have is that just one handle has a rubber coating—coating both handles would be a benefit.

Choosing the best caulking gun might seem like a straightforward proposition, but there is actually quite a bit to know about these tools. From the type of rod, power vs. no power, thrust ratio, and more, it’s worth doing a bit of research. The following are some of the most important factors to consider when searching for the best caulking gun. Caulking Gun Type There are different sizes of caulking guns. The standard caulking gun size is 10-ounce (which all of the caulking guns on this list are), but larger 29-ounce caulking guns do exist for heavy-duty applications. Why Trust Bob Vila Standard design and lightweight yet sturdy construction have made this gun the industry standard for many years.

Even with all those features, it was the tool’s grip that really stood out during testing. The two rubber over-molded grips were extremely comfortable and easy to squeeze, despite not having a tremendous thrust ratio. Also, we liked that we could cut the tips of our caulking tubes and puncture the seal with this caulking gun. The smooth rod was easy to adjust and release, too. The one thing we didn’t like about this caulking gun was that it’s not as “no drip” as it advertises. It definitely dripped a little for us. 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. Admittedly, it took us a little while to dial in this caulking gun’s pressure regulator, which did cause a bit of a mess at first. But, once dialed in, it was wonderful during testing. Releasing the trigger immediately drops the pressure behind the tube, and as a result, there’s very little dripping. Also, once we adjusted the regulator, it offered consistent and smooth pressure. In addition to an air compressor, it requires a hose for operation. Battery powered: This bad boy has removable batteries and a charger, so users can run a bead of caulk in locations where electricity isn’t available, typically running 2 to 3 hours per charge. If there is a lot of caulking to do, consider investing in an extra battery so the juice won’t run out before the job is done.

First, we took note of features like rods, built-in cutters, puncture wires, and rubber grips. Not all caulking guns had these features, so it was important to compare them before testing. 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. Welded steel, epoxy-coated frame for a strong a durable build & will be a long-lasting addition to your tool bag.Bob Vila has been America’s Handyman since 1979.

Thrust ratios run from 3:1 to 28:1. Guns with lower ratios are suitable for dispensing thin types of caulk, such as water-based latex caulk, while higher thrust ratios are needed for dispensing more viscous types of caulk, such as epoxy sealants. Revolving Frame 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.
