The Zymurgoes 1350 Rubber Torque Arrestor is a well-engineered accessory designed to reduce the twisting movement that occurs when a submersible well pump starts. This twisting can cause the pump assembly to contact the drop pipe and well casing, leading to wear or damage. The arrestor is ideal for homeowners, farmers, and technicians who want to extend the life of their well pump system.
Its standout feature is the adjustable design that fits well casings from 4 to 8 inches in diameter, making it compatible with a wide range of residential and agricultural installations. The flexible rubber construction cushions the pump and absorbs vibration, while the dual stainless steel clamps provide a secure, corrosion-resistant hold. The two-piece installation is a major plus, as it wraps around the drop pipe without requiring the entire assembly to be removed.
Build quality is solid: the molded rubber feels durable and the clamps are robust. The product is lightweight at under 2 pounds and includes all necessary components. However, the rubber may degrade over time if exposed to aggressive water chemistry or extreme temperatures, though this is common for similar products.
One potential drawback is that it only fits 1-inch and 1-1/4-inch drop pipes, so those with non-standard sizes will need to look elsewhere. Additionally, since the product has no customer reviews yet, long-term performance data is unavailable. That said, the design follows proven 1350-style torque arrestor principles.
Overall, the Zymurgoes 1350 offers excellent value for its price, combining versatility, ease of installation, and essential torque control. It is a smart investment for anyone maintaining a submersible well pump system and wanting to prevent unnecessary wear on pipes and casings.
Buying Guide: What to Look for in a Torque Arrestor for Submersible Pump
Material and Durability
The material of a torque arrestor determines how well it withstands years of submersion and temperature swings. Molded rubber is the most common choice because it remains flexible even in cold water and provides a firm grip around the drop pipe. Some models use thermoplastic compounds that stay pliable in extreme cold, like the Plumb eeze from BOSHART. Stainless steel clamps are a must for corrosion resistance; all products we reviewed include them. For long-term reliability, choose an arrestor with a robust two-piece rubber construction that compresses evenly against the well casing.
Fit and Adjustability
Not all well casings are the same diameter. Look for a torque arrestor that fits your drop pipe size (typically 1 inch or 1.25 inches) and expands to match your casing width. Most models adjust from 4 inches to 8 inches, covering the vast majority of residential and agricultural wells. The Innconee and Simmons arrestors are designed to expand and compress so they contact both sides of the casing, preventing any sideways movement. If you have an unusually large or small casing, double-check the product specifications. For more on matching components, explore our well pump kit for home guide.
Ease of Installation
You want a torque arrestor that installs quickly without special tools. All the products here are two-piece designs that wrap around the drop pipe and secure with clamps. No need to remove the entire pipe assembly. The Innconee models are especially straightforward: you simply position the rubber pieces, tighten the stainless steel clamps, and compress the arrestor to fit the casing. The Zymurgoes 1350 Rubber Torque Arrestor also emphasizes simple two-piece installation. If you are pairing the arrestor with a new pump setup, a well pump with soft start can further reduce torque stress.
Clamp Quality and Security
The clamps hold the arrestor in place, so they must be strong and corrosion-proof. Every product in our list includes two stainless steel clamps. The Merrill MFG torque arrestor and the Simmons Rubber Torque Arrestor are supplied with clamps that have a proven track record. Some users prefer the wider clamps found on the Innconee and BOSHART models because they distribute pressure more evenly. A secure clamp prevents the arrestor from slipping down the drop pipe over time, maintaining consistent protection.
Final Thoughts
After evaluating seven torque arrestors, we recommend the 2 Pcs 1350 Rubber Torque Arrestor for Pump from Innconee for its exceptional versatility and value, especially if you need two units for a dual-pump system or a spare. For a time-tested, budget-friendly option, the Rubber Torque Arrestor from Simmons delivers reliable performance with over 880 verified ratings and fits most standard wells. Both are easy to install and built to last, giving you peace of mind every time your pump starts.
Frequently Asked Questions
What does a torque arrestor do for a submersible pump?
A torque arrestor is installed directly above the submersible pump to absorb the twisting force when the pump starts. It prevents the drop pipe from banging against the well casing and protects the electrical cable from abrasion, extending the life of your pump system.
How do I know which size torque arrestor to buy?
Most torque arrestors fit 1-inch or 1.25-inch drop pipes and expand to accommodate well casings from 4 to 8 inches in diameter. Measure your drop pipe outer diameter and your casing inner diameter to confirm compatibility. If you have a non-standard size, check the product description for exact dimensions. For more on sizing your entire system, see our well pump for pressure tank.
Can I install a torque arrestor myself?
Yes, installation is straightforward. You wrap the two rubber halves around the drop pipe above the pump, secure them with the provided stainless steel clamps, and then compress the arrestor so it contacts the well casing. No special tools are needed. Always follow the manufacturer instructions for your specific model.
Do I need a torque arrestor for a deep well pump?
Yes, especially for deep wells where the drop pipe is long and the torque forces are greater. A torque arrestor helps stabilize the pump assembly and reduces wear on the pipe threads and cable. It is a low-cost insurance against expensive repairs. For additional protection, consider pairing it with a soft-start controller, which we cover in our well pump with soft start.
