Different Types of Hose Couplings [With PDF]

The purpose of this presentation is to provide brief information about different types of hose couplings which are used in oil & gas applications.

Purpose of Couplings:

Couplings can be used in various conditions like:

  • For loading & unloading tanker connection.
  • For purging as well as flushing connection.

Different Types of Hose Couplings: 

Hose Coupling can be classified into the following categories:

  • Elaflex
  • TODO
  • Cam and Groove (Camlock) Couplings
  • Avery Hardoll dry-break couplings &
  • Carter couplings

Let me show 1 by 1 in detail.

Elaflex Couplings:

  • Elaflex coupling sizes – ½” to 4”
  • Type of pipe connection – threaded & flanged
  • Available Pressure classes – 150# & 300# (Working pressure up to 25 bar)
  • The material of construction – Brass (for non-sour service), SS (for sour service)
  • Manufacturing Std. – API RP 1004 / EN 14420

TODO Coupling:

  • Available sizes – 3/4” to 6”
  • Type of pipe connection – threaded & flanged
  • Pressure class – 150# & 300# (Working pressure up to 25 bar)
  • The material of Construction – Brass, SS, Aluminium, Hastelloy C & other on request
  • Manufacturing Std. – EN 13480 and EN 13445
  • TODO couplings are used for tanker unloading connection into a tank/vessel, because of the integral check valve.
  • Elaflex couplings are used for tanker loading connection from a tank/pit.

Cam & Groove (Camlock) Couplings:

  • Available sizes – 1/2” to 6”
  • Type of pipe connection – threaded
  • Pressure class – 150# (Working pressure up to 17 bar)
  • The material of Construction – Brass, SS & Aluminium

Carter Couplings:

Carter Couplings are used in the following applications:

  • LNG tanker refueling
  • Aircraft refueling
