Paragon Guardian Insulated Cooling Water Y-Hose
$164.99
Paragon Guardian Water Y-Hose Set
Paragon’s innovative Guardian Water Supply/Return Y-Hose Set is designed to simultaneously run cooling water to two separate cooling garments. At 8 feet in overall length, the Guardian Y-Hose is the ideal length to suit most applications, although each of the three "legs" can easily be shortened to customize fit.
The Paragon Guardian Y-Hose is insulated to keep your cooling garments supplied with icy cold water from a Paragon Viking. Arctic Wolf, or Arctic Fox cooler. The supply side of the Paragon Guardian Water Supply Hose delivers cooling water to the tubing inlets of your garments, while the return side of the hose set returns water warmed by body heat back to the cooler to be re-chilled and recirculated.
Foam insulation acts as a thermal barrier to properly maintain the temperature of the water being supplied to your cooling garments. Paragon Guardian male connectors at the cooler end of the hose set are designed for emergency release, allowing you to easily disconnect with a quick pull on the hose set or garment.
Paragon Guardian Supply Y-Hose Details
Manufacturer: Paragon
Overall length: 8 feet (2.4 meters)

Frequently Asked Questions (FAQs)
Q: Will this kit fit my Stilo ST5 GT helmet?
A: Yes! While these kits are designed for the FN models, they work perfectly with Stilo GT helmets as well.
Q: Do I need to modify my helmet to install this communication kit?
A: No modifications needed. These non-integrated kits drop right in—no cutting, drilling, or special tools required.
Q: What’s the difference between the boom mic and button mic options?
A: Boom mics sit directly in front of your mouth for maximum voice clarity—great for open cockpits or louder race environments. Button mics are smaller, mounted inside the liner, and offer a clean, low-profile setup for closed cockpits.
Q: Can I use my own racing earbuds?
A: Absolutely. All kits include a 3.5mm jack so you can use your preferred in-ear monitors.
Q: IMSA vs NASCAR plug—how do I know which one I need?
A: It depends on your radio system. IMSA uses a 4-channel (TRRS) connector, NASCAR uses a 3-channel (TRS) connector. Check your team's setup to confirm compatibility.

A Note on Cleaning Anti-Fog/Anti-Scratch Shield
Anti-scratch/anti-fog shields require special care in order to preserve the coatings on the inside of the shield. Only use Acrysol Shield Cleaner to clean your shield, inside and out. Do not use glass cleaner containing ammonia (like Windex) as this can harm both the anti-scratch coating on the outside of the visor and the anti-fog coating on the inside. In a pinch, you're better off using water and a clean microfiber cloth to gently clean your Stilo shield.

High quality, Anti-fog visors shaped for the Stilo ST5 GT helmets. The Stilo ST5 series is unique in that the shield lock is located in the center position of the shield. The shield lock is released by squeezing the outboard sides together and that will then release it from the mount stud that is located in the center of the helmet. The reason for this is to "clean-up" the sides of the helmet where a side impact in a head containment seat may grab parts of the helmet. All Stilo ST5 shilds have the center release mechanism installed on it.All Stilo ST5 shields are treated with an anti-fog treatment and they do require special care. The best result we have by far is the Stilo Visor cleaner. Liberally spray the outside of the visor with the cleaner, and wipe in a single swipe with a micro fiber towel until clean and dry. If fingerprints or dirt remain, repeat as needed. A back and forth wiping motion will tend to leave lint from the rag on the visor, so the single pass works best. Repeat if necessary, but usually one pass works great.Stilo Visor Care: Do not use Windex or any glass cleaner containing ammonia, as this can harm the anti-scratch coating on the outside of the visor, and the anti-fog coating on the inside of the visor. This is the official Stilo Visor Cleaner.
