Spiral wound gaskets are fabricated from thin metal strip sandwiched
between layered of non-metallic filler. SWG has alternative spiral layers of thin metal sheet and filler material. As these layers are wounded in
continues spiral forms, these types of gaskets are known as spiral wound gasket. These gaskets are extremely popular due to the wide variety of available styles and sizes.

A-Z guide to grease fitting types, sizes &
thread identification
Most of the time, finding the ideal grease fittings for your use is easier said than done.
The reason is that they come in many different types, sizes, and distinctive functions.
Although grease fittings are fundamental to proper machine lubrication, harm and
damage could ensue if they are misused. Spotting the most suitable grease fitting may
seem like a challenging task but take it easy!
With this article, you will learn how to identify grease fittings and navigate your grease
fittings selectionproperly. So, let’s dive in and find the right parts for you!
I. Grease fitting basics
1.1. Functions
A grease fitting, sometimes called a Zerk fitting, grease nipple, or Alemite fitting is a
small metal fixture used on mechanical assemblies. It provides lubrication to internal
parts without leaks or overspill. Adding lubricants to mechanical systems helps improve
their efficiency.
The grease fittings remain closed until the pressure from the grease gun opens them to
dispense grease into the system’s moving parts, greatly reducing the possibilities of
machinery failure.
1.2. Design
Grease fittings are set in place by a threaded connection. Inside the fitting, a small captive bearing
ball is pushed against a retaining spring by the grease gun’s pressure.
The setup operates as a pathway that allows the grease to flow to the bearing. When the pressure
releases, the bearing ball returns to the tip.
3. GMUNDCARS.COM
GMUNDCARS.COM | timmiller.gmcars@gmail.com
The bearing ball blocks dirt and other wastes from entering the bearing. It also acts as a check valve
that creates a seal, obstructing the grease from flowing back out of the fitting.
Grease fittings are attached to a grease gun to administer a pressure-resistant connection. Also, they
have a channel behind the opening that runs straight to the area where you need to grease.
1.3. Material
Most grease fittings are made of zinc-plated steel, stainless steel, carbon steel, mild steel, or brass.
Some variations also have a supplemental coating of chromate to limit corrosion and improve
durability.

II. Grease fitting thread identification
2.1. Types of grease fitting threads
There are many types of grease fitting threads available for use. But how can you be certain about the
functionality of your grease fitting thread assembly? Let’s learn how to identify common thread
types and how to choose the best for your application!
Threads are the ridges that wrap around the cylinder or cone and form a coil. There are six common
different types of threads:
+ BSPP (British Standard Pipe Parallel)
+ BSPT (British Standard Pipe Taper)
+ Metric parallel
+ Metric tapered
+ NPT/NPTF (National Pipe Thread/National Pipe Thread Fuel)
+ UN/UNF (United/United Fine)

GMUNDCARS.COM | timmiller.gmcars@gmail.com
2.2. How to identify grease fitting thread
Keeping track of the six commonly used types of threads is not a simple task. It’s easy to select an
incorrect part accidentally, but the following text offers a few ways to get to the correct choice. Here
are some ways to identify the threads on your grease fittings:
With a grease fitting gauge
Using a specific tool called grease fitting thread gauge is the easiest method to determine the thread
on a grease fitting.
Grease fitting gauge – the easiest method to determine the thread on a grease fitting
This special tool helps save time and grants a simple way to distinguish one grease fitting thread
from another. It includes the standard metric sizes such as the UNF, the American standard, the
British standard, and many more.
Without a grease fitting gauge
Although having a grease fitting thread gauge is convenient, you can still identify the correct grease
fitting thread through various ways without needing this tool.
Parallel vs. Tapered
To determine if the thread is parallel or tapered, focus on its diameter. If the thread’s diameter runs
straight from top to bottom, the thread is parallel. But if the thread’s diameter gets narrower towards
the bottom, the thread is tapered.
7. GMUNDCARS.COM
GMUNDCARS.COM | timmiller.gmcars@gmail.com
Thread pitch
The optimal way to compare the numerous threads is to use a pitch gauge
The thread pitch is the number of threads per inch. A pitch gauge measures the distance between the
individual crests or the pitch of a thread, and it is the optimal way to compare the numerous threads.
Thread Type Pitch Size
BSPP 11, 14, 19, 28
BSPT 11, 14, 19, 28
Metric parallel 1.0, 1.5, 2.0
Metric tapered 1.0, 1.5, 2.0
NPT/NPTF 11½, 14, 18, 27
UN/UNF 12, 14, 16, 18, 20, 24
8. GMUNDCARS.COM
GMUNDCARS.COM | timmiller.gmcars@gmail.com
Thread diameter
A caliper tool is handy for measuring the thread diameter of your grease fitting. In addition, it is a
simple two-part tool that can measure the internal and external diameters of objects.

Use the lower jaw of your caliper to measure the external diameter of your grease fitting. The
diameter of your grease fitting would be the point where the 0 (zero) mark of your caliper’s slider is
pointed at.

4. Grease fittings tips
Before finding the right grease fitting, you must first determine what kind of grease
fitting thread you will use. You can choose from several kinds of thread components
available. The thread fittings are commonly used in the BSPP, BSPT, metric parallel,
metric tapered, NPT/NPTF, and UN/UNF.
After determining your fitting thread, then you can now choose from the many different
kinds of grease fittings, according to each of their particular features. There are also
various types of grease guns to use alongside grease fittings, including the lever, pistol-
grip, pneumatic, and cordless guns. Most of these guns are appropriate to use for any
application.
More importantly, keeping your grease fitting in its tip-top shape will help maintain its
effectiveness. Doing so will also help you save a ton of money in the long run. Here are
some tips on how you can properly maintain your grease fitting.
Use a clean rag to wipe your fitting before installing it. A lint-free cloth would be
the best for this job.
Regularly check your grease fittings and immediately replace any defective ones.
As much as possible, use a common fitting type and size for similar applications.
Use label tags to help you remember the type of grease the flows through each of
your grease fittings.
Know the delivery capacity of your grease fitting and make sure not to exceed
them.
Maintain your grease gun properly as well If you are using one. Avoid storing it in
moist and dirty areas. Cover them with a thick cloth or store them inside a hard
case if possible.
Exercise extra caution and take safety measures when using your grease gun and
grease fitting.
After using your grease gun, always wipe down your fitting to avoid
contamination of dirt and moisture.

5. FAQs
1. Why does my grease gun get stuck in the fitting?
The gun gets stuck in the fitting because it is clogged by debris or hardened grease. It
would help if you clean grease fittings and grease guns before use to avoid the chances of
dirt being brought inside the bearing. Make sure the fitting is free of dirt before locking
the coupler to the zerk, and do not combine old grease with new grease.
2. What do I do if my grease fitting won’t take grease?
Inspect the following if the grease fitting won’t take grease: If the fitting nipple is
damaged, replace the fitting. But if the fitting is not damaged, it is obscured by debris that
prevents the flow, and you should replace the fitting. If there seems to be no damage,
then use an impact fitting cleaner to break down the clogs with compressed fluid
chemically.
3. How to remove the grease gun from zerk fitting?
Make sure to release the pressure on the fitting by tilting the coupler at an angle to break
the seal or loosening it with a wrench. Besides, after releasing the pressure, remember to
twist the coupler back and forth.
4. How to attach a grease gun to a zerk fitting?
First, make sure that the grease gun and the zerk are dirt-free before fastening the nozzle
to the fitting. Then, angle the coupler to the fitting and press down. Secure the connection
by tightening the nozzle on the fitting, and when the coupler clicks into place, start up the
grease gun, and let the lubricant flow.
