There are some posts on driver cooling (thanks William). I had purchased some couplers awhile back and saved the part numbers. From my notes...

There are a few different styles of disconnects we see with cooling and hydration/drinking options in race equipment. Most connectors are manufactured by CPC (Colder). Most are using 1/4” ID tube connectors though CoolShirt may be 5/16” in some cases.

Connectors come in two varieties: valved (aka “dry break” or “shutoff”) and non-valved. Both male and female couplers are available in valved and non-valved varieties e.g. CoolShirts use all valved connectors on each coupler; CamelBak reservoirs may only use it on the female side. Valved connectors can be recognized by the smaller spring loaded nozzle on the tip (these are not present non-valved connectors). Valved/non-valved can be used interchangeably. Two downsides with valved connectors (1) they cost more, and (2) you may need to purchase the male/female counterpart to ensure proper drying (and avoid colonization).

There are a few different product lines in different coupler diameters. These are not universal or interchangeable. However, you can readily create adapters with couplers on two ends to, say to use a F.A.S.T. shirt with a CoolShirt cooler for example (works great!).

The manufactures of this driver gear will generally offer connectors and adapters for sale, and some Track HQ sponsors may sell them.

Anything with a metal latch on the female side is probably the PLC (1/4”) or PMC (1/8”) series. If it’s a plastic latch it’s probably the APC series.

CPC Product Lines (among others):

Tips

Leaks? Try replacing the male connector o-ring. These wear out. They’re typically 1/16” thickness, BUNA type. You can find these for a few cents at your local hardware store. Keep extras in your track gear.

Use soapy water in driver cooling systems as your medium (in place of cooling additives). A few drops of liquid dish soap is all it takes. It also lubricates the pump.

Keeping it Clean: Buy an extra set of female connectors. Use these to drain the shirt. Run low pressure air through one end to drive the water out the other end. Sometimes simply holding one end higher is enough to get a syphon going. This will help keep your shirt like new. I store the shirt with these extra plugs in place.

Tubing looking fuzzy? Molecule wash works as an excellent cleaner. Use it in place of soap for the medium and let the pump run. A couple ounces are plenty. Running it for a 25 minute race will usually do the trick. Before long the tubes will look new. Don’t use bleach. For hydration (like Camelbaks) use dish soap or oxygen cleaner - most of the time a rinse with plain water is sufficient for storage.


Good Luck!
