Description

Radium RADIATOR CAP, TYPE-A, 1.5BAR, BLACKThe radiator cap is an essential part of an upgraded cooling system. Radium caps are engineered to safely improve cooling efficiency by managing the boiling temperature. A higher radiator pressure effectively raises the coolant boiling point, providing an extra safety margin and preventing air pocket cavitation at the water pump. NOTE: Traditionally, "radiator" caps are mounted to the radiator but can also be found on coolant expansion tanks (below).

The radiator cap is an essential part of an upgraded cooling system. Radium caps are engineered to safely improve cooling efficiency by managing the boiling temperature.

NOTE: Traditionally, "radiator" caps are mounted to the radiator but can also be found on coolant expansion tanks (below).

Each OEM replacement radiator cap is manufactured from stamped stainless steel for durability. All 18-0076-X1X radiator caps are electroplated black.

Unlike OEM caps which use natural rubber gaskets, these radiator caps feature premium silicone sealing elements for long lasting durability.

TYPES
Radium radiator caps are designed for mini size (32mm ID) radiator necks only. Available in 2 common styles (Type-A and Type-B).

Bummed
Color: Basic
Way smaller than expected so I gave it to a friend with a smaller dog. It lasted all of 2 days and it was destroyed. Not chew resistant at all.

Fun Interactive Toy That Works as Advertised
Color: Basic, Color: Basic
I picked this up for my dog and have been pretty happy with it overall. The ball does exactly what it's supposed to do, rolling and bouncing around to keep my dog interested and active. One thing I noticed right away is that it's a little larger than a standard tennis ball, which may be a consideration depending on the size of your dog. For my dog, the size wasn't an issue and actually made it easier to spot during play. The slightly larger size helped keep it from going under our sofa. Recharging is simple. The ball opens easily to access the internal charging components, and I appreciate that the manufacturer included a keyed assembly system. The pieces only fit together the correct way, so there's no guessing when putting it back together after charging. The build quality seems solid, and it has held up well so far. My dog enjoys chasing it around, although like most toys, it doesn't hold his attention forever. Still, it's a nice way to provide some extra stimulation and exercise. Overall, it's a well-designed interactive toy that functions as intended.

Awesome interactive dog toy.
Color: Basic, Color: Basic
This interactive dog toy is larger than the similar, smaller, older dog toys I used to buy. This ball has about a 1/2 inch layer of what feels like tough rubberized foam. The outer shell is stiff, but soft enough for the dogs to sink their teeth into and carry around. I have a small Boston and a medium mixed breed that both enjoyed playing with the toy. It was quick to charge and the battery seems to last a while. It will automatically turn off after some inactivity to save the battery, but will come back to life if it is nudged. Although, after a 30 minute period of inactivity, it will stay off an you have to unscrew the halves to manually turn it back on again. I wish it would just stay in the sleep phase so the dogs can revisit it the next day and trigger it back on again, instead of it turning off completely. Either way, the toy feels solid and is quality material. It has lasted longer than the multiple other smaller interactive balls I have purchased for my dogs in the past. It is good value for the money and I will purchase more so the dogs don't fight over this one. The included instructions are easy to follow, and it comes with a charging cable as well. I recommend.

Poor design and durability
Color: Basic
Product does not stay connected. Very easily comes apart when dog plays with it because he uses his mouth and paws and manages to twist the two halves apart. I want to return it but I do not see that this is an option.
