How do you install a left right coupling?
The trick for left- and right-hand fittings and couplings is to get the correct bite the first time. The way to do that is to insert one side of the nipple/coupling and hand-tighten. Count the number of turns to get it to hand-tight. Then take apart and do the same on the other side.
How do you connect galvanized pipes without threads?
Use a stainless steel coupling if the galvanized pipe is in a damp position to avoid problems associated with rust. Unthreaded galvanized pipe connects together using a coupling. Connecting together galvanized pipes that are non-threaded uses a coupling that creates a sealed joint.

What is the maximum pressure of a dresser?
Other consideration is pressure rating. Dresser couplings are rated from 150 psi to 2250 psi maximum working pressure. Dresser light pattern couplings are rated up to 150 psi. Dresser style 65 and style 90 couplings are considered 150# and 300# couplings respectively. Refer the size and dimension table to look up the pressure rating of a bolted coupling. Generally, as the size goes up, the pressure rating goes down. Any coupling with 150 psi working pressure is a light pattern coupling.
What type of coupling is used for gas lines?
If you are repairing a gas line, style 90 universal coupling is very popular to repair gas lines. If you are repairing a PVC or PE pipe or any combination of steel and PVC/PE pipe, style 90 universal coupling has a lock ring to prevent from pipe pull out.
How does temperature affect gaskets?
Temperature mainly affects the gasket and pressure rating of the coupling. Higher the temperature, lower the pressure rating. Different gaskets are rated for different temperatures. Dresser makes lifetime® gaskets but factors that can affect the performance of gasket are temperature “cycle” that can result in compression set, abrasive line content that can damage the lip of seal and combination of chemical compatibility, temperature and pressure. Generally speaking, anytime the temperature is above 200 deg F, you should pay close attention to your selection of gasket, gasket chemical compatibility and pressure.

Style 65 is very popular in industrial installations and repair, especially for tight spaces where threading, bolting or welding is not a good option. Style 65 is also maintenance friendly and can be easily disassembled to access the pipe, change gasket in the coupling or perform line repairs. Dresser style 65 is available as;
What is a 62 coupling?
Style 62 Coupling: Style 62 coupling should be used where you want to connect two pipes of different sizes or steel pipe to a cast iron pipe. Choices are limited to what reduction you can have so it is important that you check the diameter range of reducing end while selecting the coupling.
How to move a gasket over a pipe?
Just slide the gasket in, have your coupling there, a little soap, a little water to lubricate the other end of the pipe.
What type of coupling is used for pipeline joints?
Use a Dresser style coupling and your pipeline joint is non-rigid, accepting expansion, contraction, vibration and line deflection.
Why use a dresser coupling?
Normally, you would use a Dresser coupling because you don’t want to thread the pipe, maybe you don’t want to flange the pipe, maybe you need access to something so you can take the coupling apart, have access to the line for whatever you need to do, to clean that out, to drain it, whatever.
What is a follower ring?

Do you need a dresser coupling to keep pipes from pulling out?
The main thing to remember, though, with the Dresser coupling, the system has to be properly anchored. You do not want the pipe to pull out and the Dresser coupling will not keep the pipe from pulling out. It does have to be properly anchored within the system.
What is a style 39?
Style 39 is ideal for industrial applications for water lines where electrical isolation is needed. Besides being used for tank hook-ups, intake or discharge lines and pumping stations, Style 39 Dresser Coupling are also widely used on gas service lines. Style 39 also comes in insulating and reducing style.
How much pressure can a dresser coupling handle?
As far as pressure, the Dresser couplings, the smaller ones, they can handle up to 1500 pounds of pressure if properly anchored. They do make a light pattern coupling that only goes up to 150 pounds; that’s only made in 2 inch through 8 inch. The bigger the coupling goes, the lower the pressure rating. That’s how it is. If you need a higher pressure than what is normal, generally they can make something out of a thicker, heavier material to do the higher pressure. They can also make restraints, if is needed, where a pipe pullout may occur because the Dresser coupling is not made to keep pipe from pulling apart. It must be within the system or it must be properly anchored with some external factor to keep the pipe from pulling apart.
How big is a dresser coupling?
Dresser couplings come as small as 1/2 inch , and go just about as large as you want them. We actually have some 108 inch that we have sold. Components of a Dresser coupling, it has two middle rings, it has two gaskets, it has however many bolts are necessary depending on the size, we have a 2 inch that’s a 3 bolt coupling over here, we have two bolt couplings. As the couplings get larger, there are more bolts and nuts. The bolt itself has an oval head that fits in the oval head of the follower. The bolt fits in, it doesn’t turn as you're tightening on the nut.
