Frequently Asked Questions
How much lighter is the 36" aluminum wrench compared to the cast iron version?
The RIDGID 836 aluminum wrench weighs approximately 11 lbs (5.0 kg), whereas the equivalent 36-inch cast-iron model (RIDGID 31035 / Model 36) weighs roughly 19 lbs (8.7 kg). That represents an approximate 40% weight reduction with zero compromise in heavy-duty torque capacity.
What is the maximum pipe capacity of this wrench?
The Model 836 has a nominal pipe capacity of 5 inches (125 mm), making it well-suited for heavy commercial mechanical, municipal utility, gas distribution, and industrial process piping.
Are replacement hook and heel jaws available for the Model 836?
Yes. Both the hook jaw (Cat # 31720) and the heel jaw with pin assembly (Cat # 31725) are fully replaceable in the field, allowing you to maintain razor-sharp biting teeth without purchasing a whole new tool.
Can this wrench be used with an extension cheater pipe?
No. RIDGID explicitly advises against using cheater bars or pipe extensions on any pipe wrench, as it alters the engineered leverage ratio, risks damaging the handle or jaw casting, and voids the lifetime warranty.
