Screw-On Hose Fittings for Hydraulic Fluid
With just a vise and a wrench, make or repair hose assemblies in the field. These fittings thread directly onto hydraulic hose, so you don't need to crimp. To install, separate the two pieces. Screw the hose end onto your hose first and then thread the two pieces of the fitting back together. These fittings compress against the hose to form a strong seal. Also known as reusable fittings, they can be unscrewed from your hose and used again.
Fittings with a female tube end swivel 360° until tightened for easy installation.
Fittings with a 37° flared end are also known as JIC (Joint Industrial Council) fittings.
Zinc-plated steel fittings are stronger and resist wear and tear better than 316 stainless steel fittings. The zinc plating resists rusting in wet environments.
Note: Fittings are only for use with hydraulic hose.

Extra-Flexible Abrasion-Resistant Hydraulic Hose with
Quick-Disconnect Socket and Female Threaded Fitting
- Temperature Range: -40° to 210° F
- Material: Blended Rubber
- Color: Black
- Threaded Fitting Swivels Until Tightened
For frequent connections, this hose has a socket end that's faster to connect and disconnect than a threaded fitting. This hose bends twice as sharply and resists wear and tear 80 times better than our basic hydraulic hose, thanks to its two layers of blended rubber. Attach it to equipment that moves or route it through tight spaces to move hydraulic fluid between pumps, cylinders, and other parts of your hydraulic system. Reinforced by two steel wire braids, it’s strong and flexible even under pressure. You can trust this hose to handle the pressures, temperatures, and fluids involved in most hydraulic applications because it meets ISO 11237-1 standards. The cover also meets MSHA (Mine Safety and Health Administration) standards for flame resistance.
Quick-disconnect plugs and sockets are sleeve-lock style. They’re compatible with couplings that meet ISO 7241-1 series B. To connect, slide back the sleeve on the socket, insert the plug, and release the sleeve. To disconnect, slide back the sleeve and pull out the plug. The socket has a shut-off valve that stops the flow when you disconnect. The threaded end swivels until tightened, so you don’t need to rotate the entire hose during installation. The threaded end meets SAE J516 and ISO 12151-5 dimensional standards.

Extra-Flexible Abrasion-Resistant Hydraulic Hose with Female Threaded Fittings
- Material: Blended Rubber
- Color: Black
- Both Fittings Swivel Until Tightened
- Temperature Range: -40° F to 255° F
The new standard for rubber hydraulic hose, this hose bends twice as sharply and resists wear and tear 80 times better than our basic hydraulic hose. Attach it to equipment that moves or route it through tight spaces to move hydraulic fluid between pumps, cylinders, and other parts of your hydraulic system. Made of blended rubber and reinforced by two steel wire spirals, it’s strong and flexible even under pressure. It meets ISO 18752, which means all sizes have the same pressure rating. This is why it’s also known as constant-pressure hose. The cover also meets MSHA (Mine Safety and Health Administration) standards for flame resistance.
It comes with female threaded fittings already attached, saving you time. Both fittings swivel until tightened, so you don’t need to rotate the entire hose during installation.
Flared fittings meet ISO 12151-5 and SAE J516 dimensional standards.

Heavy Duty Hydraulic Hose with Female Threaded Fittings
- Temperature Range: -40° F to 255° F
- Material: Blended Rubber
- Color: Black
- Both Fittings Swivel Until Tightened
Internally reinforced with four steel wire spirals, this hose resists bursting from rapid changes in pressure and flow. It’s often used with bulldozers and drilling equipment to move hydraulic fluid between pumps and valves. It meets ISO 18752-CC, so it’s passed a test with 500,000 quick pressure changes. This ISO standard also means that all sizes have the same pressure rating, which is why this hose is sometimes known as constant-pressure hose. Made of blended rubber, it bends twice as sharply and resists wear and tear 80 times better than our basic hydraulic hose. Route it through tight spaces or attach it to equipment that moves without worrying about it cracking or kinking. The cover meets MSHA (Mine Safety and Health Administration) standards for flame resistance.
To save you time, this hose comes with female threaded fittings already attached. Both fittings swivel until tightened, so you don’t need to rotate the entire hose during installation. The fittings also meet SAE J516 and ISO 12151-5 dimensional standards.

Heavy Duty Hydraulic Hose with Male Threaded Fittings
- Temperature Range: -40° to 255° F
- Material: Blended Rubber
- Color: Black
To handle rapid changes in pressure and flow without bursting, this hose is reinforced with four steel wire spirals. It’s often found on earth-moving and drilling equipment to transfer hydraulic fluid between pumps and valves. It meets ISO 18752-CC, so it’s passed a test with 500,000 quick pressure changes. This ISO standard also means that all sizes have the same pressure rating, which is why this hose is sometimes known as constant-pressure hose. Made of blended rubber, it bends twice as sharply and resists wear and tear 80 times better than our basic hydraulic hose. Route it through tight spaces or attach it to equipment that moves without worrying about it cracking or kinking. The cover meets MSHA (Mine Safety and Health Administration) standards for flame resistance.
It comes with male threaded fittings already attached, so it's ready to use right out of the box.
