Parmelee 74128 G4 4-1/2″ OD Girth for H4 Handle, Extra Heavy Gauge Pipe Wrench

What is the Parmelee 74128?

The Parmelee 74128 (G4 4-1/2) is a G4 girth for pipe, tubing or rod with a 4-1/2″ outside diameter (OD). The girth is the 3-piece head of the Parmelee pipe wrench that grips the pipe, tube or rod 360 degrees around its outside diameter. It mounts on the H4 extra heavy gauge handle (Parmelee 71004), sold separately.

How does the Parmelee wrench grip without marking the pipe?

The Parmelee wrench (sometimes spelled Parmalee), also called pipe tongs, friction tongs or a friction wrench, has no teeth. Its girth surrounds the pipe completely, the way a hand closes around it, and the ratchet action of the handle takes a new grip with each pull. That is why it is used on highly polished pipe and piston rods and in tight spaces where a chain or toothed wrench would mar the finish.

The girth of the No. 4 wrench is cast high carbon alloy steel, toughened and hardened by heat treatment. Standard girths like this one have a polished finish.

Which pipe size does the Parmelee 74128 fit?

It fits 4-1/2″ OD only. Parmelee makes a separate girth for each diameter of pipe, tubing or rod, and a girth cannot be used on any other diameter. Measure the outside diameter before ordering; for pipe known by its nominal size, see the IPS girths.

Standard G4 girths: 3-1/4″, 3-7/16″, 3-1/2″, 3-5/8″, 3-3/4″, 3-7/8″, 4″, 4-1/8″, 4-1/4″, 4-3/8″, 4-7/16″, 4-1/2″, 4-5/8″, 4-3/4″, 5″, 5-1/8″, 5-1/4″, 5-3/8″, 5-1/2″, 5-9/16″, 5-5/8″, 5-3/4″, 5-7/8″, 6″ OD; 3″, 3-1/2″, 4″, 5″ IPS. Across the four wrench sizes, metric girths from 19 mm to 172 mm and other sizes are available on request, quoted separately.

How do you use and care for a Parmelee wrench?

• Use the wrench only as supplied. Parmelee warns never to modify it and never to fit a longer handle or an extension cheater for more leverage: that overstresses and damages the girth and handle, and the warranty does not cover it.
• Clean the wrench after use, apply a light coat of oil against rust and store it in a dry place.
