Easily drain the water from your large diameter hose with our system using an air compressor, Air Raid hose, manifold, pig catcher and pigging balls and bullets.
Our complete pigging system is safe and efficient for your crew to use. Instead of breaking down the couplers and lifting heavy hose, your crew can shoot the pigging balls or bullets through the hose with an an compressor and air hose. This process drains the water and cleans the hose at the same time.
When you’re traveling to the fire, the last thing you need is your hose and nozzles bouncing and rolling around, making your important supplies difficult to find. A mounting plate allows for compartment organization of appliances. The Storz Mounting Plates from U.S. Coupling allow you to mount fire nozzles in the compartment to ensure a stable ride while in storage, as well as creating stability and easy deployment when used on hose loads. All of our lightweight adapters are made from custom manufactured, aircraft grade 6061-T6 seamless, aluminum extrusions. These Mounting Plates are available in diameters ranging from 4” to 8”.
As a connector for large diameter hose the Storz x Rigid Female Thread Adapter is ideal for use in directly connecting LDH supply lines to attack lines, particularly when stepping down in diameter size. The female NH thread on the adapter quickly connects and disconnects from the male NH thread on the lay-flat hose.
Storz heads provide maximum strength, while the rigid female threaded adapter provides little to no movement or separation. Machined from forged 6061 -T6 aluminum and hardcoat anodized to military specifications, this firefighting adapter uses either National Hose Thread (NH) or National Pipe Thread (NPT) threads. The Rigid Female Thread diameter ranges from 2.5” to 12” and the Storz diameter ranges from 4” to 12”.
As a connector for large diameter hose the Storz x Rigid Male Thread Adapter is ideal for use in directly connecting LDH supply lines to attack lines, particularly when stepping down in diameter size.

Storz heads provide maximum strength, while the rigid male threaded adapter provides little to no movement or separation. Machined from forged 6061 -T6 aluminum and hardcoat anodized to military specifications, this adapter uses either National Hose Thread (NH) or National Pipe Thread (NPT) threads. The Rigid Male Thread diameter ranges from 2.5” to 12” and the sexless Storz diameter ranges from 4” to 12”.
The Storz x Long Handle Swivel Female Thread is ideal for use in firefighting for hydrant connections. The long handle adapters allow connection to a hydrant or large discharges on fire trucks or pumps. The handles are used to create a tight fitting to the water supply source.
A swivel fitting is a hose connection that allows the hose to spin or swivel without twisting on the end of the hose. This stops the fire hose from kinking when in use and helps to unkink it when you first walk out the hose. The long handle on this Female Swivel fitting provides more surface to grip for easier use. U.S. Coupling’s female adapter is made from quality aluminum, and the Storz fitting is made from steel from North America and is available in diameter sizes ranging from 4” to 6”. The Long Handle Female Swivel adapter is available in diameter sizes from 2.5” to 6”. Both fittings have a National Hose Thread (NH) thread.
Ideal for use in quick deployment of hose without rolling or twisting, the Storz x Rocker Lug Swivel Female Thread is hard anodized and powder coated for corrosion resistance and protection.
A swivel fitting is a hose connection that allows the hose to spin or swivel without twisting on the end of the hose. This stops the hose from kinking when in use and helps to unkink it when you first walk out the hose. The Storz x Rocker Lug Swivel features raised ridges to allow for better grip when connecting or disconnecting couplings. Made from custom manufactured, aircraft grade 6061-T6 seamless, aluminum extrusions, this fitting uses an National Hose Thread (NH) thread type. The female thread diameter ranges from 2.5” to 8” and the Storz diameter ranges from 4” to 12”.
