The Besttruck 1350 Rubber Torque Arrestor is a practical add-on for any residential well system using 1" to 1-1/4" drop pipe. It is specifically designed for well casings with an inside diameter of 4" to 8", making it a versatile choice for many homeowners. This torque arrestor acts as a shock absorber, preventing the motor start-up torque from pushing the pump against the casing, which can cause wear or damage over time.
Standout features include its high-grade molded rubber construction and double stainless steel clamps. The rubber provides excellent abrasion and corrosion resistance, ensuring the device holds up well in the harsh environment of a well. The clamps keep the arrestor securely in place, even under repeated stress from pump cycling. Installation is straightforward: simply place the arrestor around the pipe, tighten the lower clamp, adjust the center portion, then tighten the upper clamp. No special tools are required.
In terms of build quality, the rubber feels dense and durable, and the stainless steel clamps resist rust. The product weighs 1.8 pounds and measures 12 x 4.1 x 3.9 inches, making it compact enough to handle easily. The black color blends in with typical well components. While the design is simple, it focuses on doing one job well: protecting your well pump from torque damage.
One potential drawback is the specific size compatibility. If your drop pipe is not exactly 1" or 1-1/4", or if your well casing falls outside the 4" to 8" range, this arrestor will not fit. Additionally, because the product has no user reviews yet, you are relying on the manufacturer's claims and specifications. However, the features align with standard torque arrestor designs, so performance should be reliable.

It is easy to install, built from quality materials, and comes with a one-year warranty. For DIY well owners looking to add a layer of protection without breaking the bank, this is a solid choice.
Buying Guide for a Torque Arrestor
Fit and Compatibility
The first thing to verify is whether the arrestor matches your drop pipe diameter and well casing size. Most models fit 1-inch to 1-1/4-inch pipes and expand to fit 4-inch to 8-inch casings. However, some are more adjustable than others. Measure your pipe and casing before buying to avoid returns. For a quiet well setup, see our quiet well pump picks.
Material and Durability
Molded rubber with stainless steel clamps is the standard for torque arrestors. The rubber must resist abrasion and corrosion from well water. Some arrestors use a two-piece design that compresses against the casing for a secure hold. Look for reinforced rubber and heavy-duty clamps that won’t rust over time.
Ease of Installation
A good arrestor should install without special tools. Typically, you place it around the drop pipe, tighten the lower clamp, adjust the center, then secure the upper clamp. Some models come with clear instructions. If you are also considering a soft-start pump, check our soft-start well pump guide for reduced torque at startup.
Number of Pieces
Some packs include two arrestors, which can be useful for deeper wells or for having a spare. A single arrestor is enough for most residential setups. Consider your well depth and whether you want redundancy.
Final Thoughts
After evaluating these options, the 2 Pcs 1350 Rubber Torque Arrestor for Pump stands out for its two-piece pack and high rating, while the Rubber Torque Arrestor from Simmons offers proven reliability at a lower entry point. Both are excellent choices depending on whether you need extra pieces or a classic single unit. Whichever you choose, installing a torque arrestor will extend the life of your submersible pump and keep your water flowing smoothly.
Frequently Asked Questions
How does a torque arrestor protect my submersible well pump?
It absorbs the rotational force when the pump starts, preventing the pump from banging against the well casing. This reduces vibration and wear, extending pump life.
Will a torque arrestor fit any well casing size?
Most models expand to fit 4-inch to 8-inch casings. Always check the product specifications for your exact casing inner diameter. For smaller casings, confirm compatibility.
Can I install a torque arrestor myself?
Yes, installation is straightforward with basic hand tools. Follow the included instructions: place the arrestor around the pipe, tighten the lower clamp, adjust, then tighten the upper clamp. No special skills required.
Do I need a torque arrestor if I have a soft-start pump?
Soft-start pumps reduce starting torque but do not eliminate it entirely. A torque arrestor still provides a safety buffer and is recommended for all submersible installations. Learn more about soft-start well pumps in our dedicated guide.
