Chapter 3: Liquid Tight Connector Parts

In this chapter, we will categorize the different components of a liquid tight connector and their corresponding functions.

liquid tight connector parts

Sealing Nut

A sealing nut for the seal tight electrical fittings is considered an inert molded elastomeric ring.

It might be reinforced internally along with an aluminum disc to remove over-compression that might take place in “O” rubber rings.

Seal

A seal is utilized to combine two parts of an engine, machine or other mechanical assemblies.

It fills the space among both parts, making a seal and filled space in the idle.

That seal stops fluid, vapor and particle leakage to safeguard and keep pressure while keeping debris out.

It also guarantees proper safety and function.

Seals are utilized in different fields and industries such as:

  • general engineering
  • aerospace
  • automotive

This is typically made of rubber.

It is position inside the body of the liquid tight connector to serve as a seal.

You see, the seal offers safe and secure coverage for the entry point of the cord and the cable.

Body

The body of the liquid tight connector has a ferrule that spreads outside the collar.

An annular ring is molded central on the ferrule.

liquid tight connector body

When a non-metallic conduit is strapped into it, there’s no restraint except for the meddling fit of the annular ring.

The main body is shorter.

Thus, liquid established in the body can’t find its way to the housing.

There’s no communication between the conduit when attached to the outside of the passage and the ferrule.

Lock Nut

A locknut at the close part of the liquid tight connector is also formed along with flats to enable wrenching.

Compression Nut

compression nut

There is a compression nut that features a vaulted top as well as a conical internal surface.

Throughout the installation, the conical surface triggers the clip by concluding the fingers.

The compression nut is created to bottom on the shoulder of the body.

Therefore, stopping any over torque.

Ferrule

A ferrule in the connector was threaded and often screwed into the conduit.

Chapter 4: How to Install Liquid Tight Connector

After understanding the different parts of the liquid tight conduit fittings, what’s next?

Well, it is time for you to know the proper installation.

Fitting installation is very simple.

Take a look at the step-by-step stainless steel liquid tight fittings installation:

Step 1

Cut the conduit end square.

Step 2

You can now apply the compression nut over the conduit.

Step 3

Slip on the split gland ring.

Step 4

You must string the body ferrule end into conduit until bottomed.

Step 5

Place gland ring in contradiction of body ferrule cavity and cord the compression nut onto the body.

Step 6

Hand tightens to make sure full gripping capability.

Step 7

Break the sealing o-ring into seat given for a liquid-tight seal through some box application.

Step 8

Secure along with locknut or to threads as needed.
