What is male end of fire hose?

Hose couplings come in three different genders: male, female, and universal. The gender of a hose coupling is easy to determine by looking at its threads. Male coupling has threads on its outside and female coupling has threads on the inside.

What is male coupling on hose?

Garden hose fittings and couplings are parts that connect garden hoses to a water source or another hose so water can flow through a system. Garden hose fittings are installed on the ends of hoses for attaching to spigots, nozzles, sprinklers, and other hoses.

What is NPT and ght?

Garden hose threads and national pipe tapers are completely different screw threads. GHT has parallel threads, while NPT has tapered threads. GHTs are for gardening and landscaping use while NPTs are for plumbing systems. Both threads do not fit each other, so you cannot use them together in one joint.

When rolling hose the male end of the hose should be?

Similar to the straight roll method, lay the hose flat and without twists. Then, fold the hose in half, with the male end on top, about two feet away from the opposite, or female, end. Complete the roll from the fold end.

What is the difference between NPT and NPSH?

Fire hoses with National Pipe Straight Hose Thread (NPSH) has 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.

Introduction to Fire Hoses

What is MPT and FPT?

MPT stands for Male Pipe Thread and MIP stands for Male Iron Pipe which both indicate a male fitting with NPT threads. FPT stands for Female Pipe Threads and FIP stands for Female Iron Pipe which both indicate a female fitting with NPT threads.

What is MPT connection?

MPT Male Pipe Thread (interchangeable with NPT) National pipe thread connection to an FPT (Female Pipe Thread) or equivalently an FIP (Female Iron Pipe). MPT the threads are located on the outside of the pipe or fitting.

What is the purpose of lugs on a fire hose coupling?

The raised ridges on the body of the male and the swivel of the female are known as rocker lugs. These lugs are engaged with spanners to tighten and loosen the couplings. The notch on the lugs is called a higbee notch or higbee cut (I have also seen it spelled higby).

What is a forward hose lay?

With the forward lay, the apparatus lays hose from a water source, such as a hydrant, to the fire location. This method consists of the apparatus stopping at a hydrant permitting a firefighter to step off the apparatus and safely anchor the supply hose. Getting the apparatus to the fire is the priority.

What is a Dutchman in the fire service?

Dutchman -- A term used for a short fold placed in a hose when loading it into the bed. This fold prevents the coupling from turning in the hose bed.

What is NPT hose?

NPT stands for National Pipe Tapered threads, also known as ANSI/ASME B1. 20.1 pipe threads. It is a U.S. standard for measuring tapered threads on threaded pipes and fittings. Threaded pipes can give an effective seal for pipes using hydraulic fluids.

Is water hose NPT?

Garden hose adapters and connectors are fittings that have a standard 3/4" garden hose thread (GHT) connection on one end and a connection with a different thread type on the other end, such as National Pipe Taper (NPT).

What size is ght?

Sizes of Garden Hose Connectors

Garden hose connectors usually come in 3/4 or 5/8-inch. It is according to the inside diameter of the hose. Garden hose fittings also vary accordingly and the most popular size is 3/4-inch or 11.5NH. This size is also perfect for commercial purposes.

What's the difference between a male and female hose connector?

A male connector is commonly referred to as a plug and has a solid pin for a center conductor. A female connector is commonly referred to as a jack and has a center conductor with a hole in it to accept the male pin.

What is the difference between male and female hose connectors?

The bolt is the male connection with the threads on the outside and the nut is the female connection with the threads on the inside. The most basic plumbing fitting is the nut and bolt to join two lengths of pipe.

What is a female hose connector?

In the US, typically a 3/4" female threaded fitting is crimped to the end of the hose that connects to the bibcock, allowing it to be simply screwed on. The other end of the hose that connects to the spray head has a 3/4" male threaded fitting.

What is a reverse lay fire hose?

A forward lay is a supply line laid from the fire hydrant or another source of water right to the fire. The opposite of that is the reverse lay, which is laying down the supply line from the source of the fire to the water supply.

What is a reverse lay in firefighting?

The Reverse Lay is typically used by the second due engine to supply the first due engine with a supply line. The second due engine stops at the scene or the attack engine, drops a supply line off to make connections and then proceeds to the hydrant.

What is a split lay?

The split lay is typically initiated by the first due engine when they recognize an access problem. The first due engine drops their supply line in an intersection or location before the confined area and then proceeds to the fire. The second due engine lays a line to the first due's supply line.

What are two types of coupling used in fire service?

What is a Minute Man load?

One such load is the “Minuteman” hose load, which is designed to aid the firefighter in getting the initial attack line in place with ease for any type of operation, be it residential, commercial, or high-rise.

What is NPT and FPT?

NPT, national pipe threads, and FPT, female pipe threads, are terms used regarding U.S. pipe standards for tapered threads. NPT are common threads used for general purposes, while FPT are a type of NPT.

What is the difference between MTP and PTP?

PTP stands for “Picture Transfer Protocol.” When Android uses this protocol, it appears to the computer as a digital camera. MTP is actually based on PTP, but adds more features, or “extensions.” PTP works similarly to MTP, and is commonly used by digital cameras.
