Storz Fire Hose Coupling

Storz fire hose coupling

Storz couplings, or fire hose fittings, have a symmetrical design with a bayonet locking system protected by a collar. Storz couplings are used for connecting either hoses or connectors together. As these couplings are symmetrical, both sides of the coupling are the same.

What type of coupling does a fire hose have?

There are three types of hose couplings, including threaded couplings, storz-type couplings, and non-symmetrical quick connect couplings. Threaded couplings are one of the commonly used in the fire service. They are a male/female set designed for use on most fire hose up to 3 inch in diameter.

What is a Storz adapter?

Storz Adapters permit connecting Storz Couplings to any threaded connection. They enable you to take advantage of the speed and ease in the assembly of the Storz system when combining it with the threads on your hose, pumper or hydrant system.

How are couplings attached to fire hose?

Fire hose end connectors, commonly referred to as couplings, are made from cast brass or extruded aluminum, which is then hard-coated. They are mechanically attached to the fire hose by utilizing a copper alloy expansion ring that traps the hose against the inside (bowl) of the coupling.

How do I connect to a Storz connection?

How does a Storz Connection work? When opposing Storz couplings are pressed together, special hooks on each coupling insert into the slots in the flange of the other. Rotating the couplings in opposite directions until they're tight (usually a quarter turn) causes the latches to engage.

What does Storz mean in German?

German: from the dialect word storz 'stalk stump' presumably a nickname for a short person. Source: Dictionary of American Family Names 2nd edition, 2022.

What are the two types of couplings on a hose?

Coupling gender Male coupling has threads on its outside and female coupling has threads on the inside.

What is a BIC coupling?

FirstRESPONSE fire hose couplings are fitted onto the ends fire hose to enable the fire hose to be connected to a fire hydrant and also allow other firefighting equipment, such as nozzles, to be attached for the purpose of fighting a fire.

What is the difference between NPT and NPSH?

Fire hoses with National Pipe Straight Hose Thread (NPSH) have the same threads per inch as National Pipe Thread (NPT), but the threads do not taper. This allows a female coupling to thread onto a NPT fitting without being a permanent connection.

What is a MacDonald coupling?

MacDonald quick action couplings are designed for high pressure compressed air or inert gas. They are widely used in oil refineries, in chemical plants for nitrogen service and in general engineering industry. They are also used with pneumatic tools and for fire hose reel service where safety is a prime concern.

What is a Storz cap?

A storz cap is used in conjunction with a storz connection to prevent debris from entering the system. It can be secured to a storz connection with a simple 1/4 turn, thus, locking it in place. Specifications: Forged aluminum T6061.

What is the female coupling on a hose?

Couplings also have what are known as 'threads' on them, which allow couplings to connect to each other securely. Female couplings have threads on the inside, and male couplings have threads on the outside, ensuring that they can easily and tightly connect.

What is a female coupling?

Female Coupling: A female coupling is a receptacle that holds the male jack in place thus performing sealing functions.

What is the connector at the end of a hose called?

A hose coupling is a connector on the end of a hose to connect (or couple) it with another hose or with a tap or a hose appliance, such as an irrigation sprinkler. It is usually made of steel, brass, stainless steel, aluminium or plastic.

What is an instantaneous coupling?

The instantaneous coupling system comprises of a male and female two part connection which are held securely in position by two internal spring loaded plunger mechanisms. The hose tails have a double rib arrangement which facilitate wire binding or hose clamps.

What is a sexless coupling?

It is sometimes referred to as a sexless coupling, because rather than having a male and a female end connected by screw threads, either identical end can be joined to any other end of the same diameter. This is also called hermaphroditic or two-way connection.

How many types of fire hoses are there?

The three basic types of fire hose are: Single Jacket. Double Jacket. Rubber-covered Lay-flat.

How do you connect a fire hose to a hydrant?

And finger tight is fine if you want to get it really tight i wouldn't recommend getting extremely

What is bowl size on fire hose?

Some large diameter hose (LDH) is dual-purpose and marketed as such, but attack hose is typically found in diameters from 1—2.5 inches, while supply hose is typically 3 inches or greater in diameter.

Is fire hose thread the same as NPT?

Fire hoses and adapters with National Pipe Straight Hose Thread (NPSH or NPS) has the same threads per inch (TPI) as National Pipe Thread (NPT) but the threads do not taper. This allows a female coupling to thread onto a NPT fitting without being a permanent connection.
