The INTERTOOL 50 Foot Professional Rubber Air Hose PT08-1721 is an indispensable accessory for any workplace that utilizes air compressors and pneumatic tools that require less air flow rate up to 7 CFM. Such tools include LVLP and mini HVLP spray guns, blow guns, staplers, nailers, riveters, inflating guns, caulking guns, grease guns, and equipment with small size pneumatic cylinders. This hose is strengthened with 3 layers to ensure it can withstand the harshest work environments. The tough rubber material can withstand sharp edges, scraping, high air pressure, cold and hot environments between -22 to 140 degrees Fahrenheit (-30 to 60 Celsius), and being run over by vehicles. While standing up to wear and tear, the hose also remains kink-free and lays flat on the ground to prevent accidental tripping or being caught on other objects in the work area. A 360 degree swivel joint on one end of the hose allows for even further manipulation taking the stress off of the user’s wrists all while keeping an uninterrupted air flow from compressor to tool. At each end of the hose there are multifunctional 1/4" standard threads that can be used on their own or attached to a variety of compatible connectors. Either end is compatible with both male and female couplers. The connectors included with the hose are lightly screwed on for ease of use out of the box. Users are advised to use thread seal tape, also known as PTFE or Teflon tape, before attaching any connectors to ensure that no air escapes while the hose is in use. All thread connectors, swivel joints, and quick connectors included with the hose are produced with the highest quality industrial brass to prevent rust, increase the product’s lifetime usage, and resist heavy impacts that would otherwise cause damage to the tool. Brass is known to be the material of choice in the industry as it outperforms and outlasts those made from steel or aluminum. You can’t go wrong with this lightweight and versatile air hose for all of your pneumatic needs.
