I chose my part based on IP rating... That Tyco is rated IP67... second best water ingress protection rating. Electrical devices will generally have an IP rating...
Ingress Protection (IP) and what it means
The IP Code (or International Protection Rating, sometimes also interpreted as Ingress Protection Rating*) consists of the letters IP followed by two digits and an optional letter. As defined in international standard IEC 60529, it classifies the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in electrical enclosures. The standard aims to provide users more detailed information than vague marketing terms such as waterproof.
Here is a chart that explains and shows IP ratings.

If you are concerned about water ingress, be sure to look at the product specification sheet before you purchase. Often times you will need to visit the actual manufacturers website to find the information you want.
The folks at AAMPGlobal, who make Stinger products, have not gotten back to me with a spec sheet or warranty information. I generally stay away from products by manufacturers who do not post this type of information for everyone to access.
I did find this statement on their website...
