RIDGID 31410 902 Torque Wrench for No Hub Cast-Iron Soil Pipe Couplings
The RIDGID torque wrench is preset with a T-shaped handle to eliminate guesswork in No Hub soil pipe installations. It ensures proper coupling tightness for strong, leak-free joints. The 5/16-inch drive tightens with a fast ratchet action until the wrench clicks, delivering an accurate 60 inch-pounds torque. Best for plumbers who need quick, repeatable torque confirmation in field installations. Caution: limited to the stated torque setting; do not exceed to avoid joint damage.
Superior Tool No Hub Torque Wrench
The Superior Tool No Hub Torque Wrench provides a straightforward option for No Hub installations. Its design emphasizes ease of use and reliability for ensuring proper torque on 5/16″ sockets. Best for tradespeople who want a no-fuss tool for quick, in-service tightening. Limitation: fewer advanced features or torque indicators beyond the basic setting.
RAPTOR No-Hub Torque Wrench 5/16 80#
The RAPTOR No-Hub Torque Wrench features a T-handle with color coding to match the correct no-hub coupling and a torque setting designed to slip when the coupling nut reaches the proper setting. A locking collar allows tightening in one direction or using it as a non-torque tool in both directions. Best for technicians who value a clear torque cue and a built-in safeguard against over-torque. Caution: the torque range is specific to 5/16″ fittings and may not suit larger or smaller couplings.
T Torque Wrench, 5/16 in Cap, 60 in lb
The Wheeler-Rex T Torque Wrench offers a 5/16″ capacity with a 60 in-lb rating. It is designed for soil pipe work with a contour red T-handle that improves grip and control. This option is best for professionals who need a compact tool that can operate comfortably in tight spaces. Limitation: not all users may require the full 60 in-lb torque, potentially leaving some joints under-tightened if misapplied.
ThreeH 2 Pack SMA Torque Wrench 5/16” Drive Size 1 Nm 8mm Opening
The ThreeH 2-Pack SMA Torque Wrench uses a 5/16″ drive with a design focused on repeatability and accuracy. The internal ball design supports precise torque, and the 90-degree bend at the torque limit helps protect connectors from damage by bending at the limit. Best for professionals who want a pair of wrenches for multi-job use and consistent torque control. Caution: the 90-degree bend feature requires careful handling to avoid misalignment in tight spaces.
Pasco 7020 No-Hub Torque Wrench
The Pasco 7020 measures torque clockwise and ratchets counterclockwise, with a retractable reversing lever. It is tailored for No-Hub installations where a straightforward, paced tightening is needed. Best for installers who require reversible operation without complex controls. Limitation: torque range is fixed to a specific setting, so verify compatibility with your coupling requirements.
Jones Stephens 5/16″ Mega No Hub Torque Wrench, 80 lb.
The Jones Stephens Mega No Hub Torque Wrench delivers an automatic release at 80 in-lbs with a 5/16″ socket and a one-way ratchet. Best for fieldwork where a reliable, controlled release is essential to protect joints from over-tightening. Use as a primary tool for routine No Hub assemblies. Caution: designed for 80 in-lbs maximum torque, so avoid using on higher-torque applications.
Buying Guide: How To Choose A 5/16 No-Hub Torque Wrench
- Torque range: Verify the torque range matches your typical No-Hub coupling requirements (60–80 in-lbs is common). Some wrenches have fixed settings, others offer adjustable ranges.
- Torque feedback: Tools with audible clicks, color cues, or locking collars help confirm correct torque and prevent over-tightening.
- Handle design: A T-handle or contoured grip can improve control in tight pipe installations and reduce hand fatigue during long tasks.
- Build quality: Look for forged steel or alloy bodies with a robust drive and a reliable release mechanism to handle repeated use in field conditions.
- Reversing and direction: Some models offer reversible operation or allow use as a non-torquing tool in both directions—consider your typical workflow.
- Compatibility: Ensure the drive size (5/16″) matches your no-hub fittings and that the end profile won’t round off bolts or nuts.
- Maintenance: Periodic calibration checks and proper storage help preserve accuracy over time.
FAQ
- What is the standard torque for No-Hub pipe couplings? Most common settings range around 60–80 in-lbs, depending on coupling size and material.
- Is a torque wrench necessary for all No-Hub installations? For many professional jobs, using a torque wrench helps ensure consistent joints and reduces leak risk.
- Can I use a 5/16″ torque wrench on other sizes? Some wrenches may support only 5/16″ drive; verify compatibility with your fittings before use.
- What should I do if the wrench doesn’t click? Stop and recheck set torque and fitment. If the setting is incorrect or the tool is faulty, replace or calibrate.
- How do I maintain accuracy over time? Store tools with no load, avoid dropping, and have periodic calibration checks as needed for professional use.
- Are adjustable torque wrenches better than fixed settings? Adjustable models offer flexibility across different applications; fixed tools can be quicker for repetitive, known-torque tasks.
