MTM Hydro Vacuum Switch - 4.5 HgMTM Hydro's European Vacuum Switches are used in a variety of methods to turn other items in a pressure washing system on or off. Typically, this switch is used for burner control and is activated by a low pressure vacuum threshold near the pump inlet where this switch is mounted on a 'T' fitting. As you disengage your gun by releasing the trigger, the pressure suddenly spikes which puts your system in bypass and eliminates the low pressure vacuum

I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it. The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch

Size: Medium

My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.

Keeps dogs busy.

Color: Orange

The dogs love this ball. They are afraid when it vibrates but as soon as it jumps and moves around, they are on it. They will play with it for quite awhile. Charge lasts for a long time. Very durable. This dog can tear anything apart but it's still in one piece.

Bad purchase 10 minute playtime

Color: Orange

This ball was bigger than the usual tennis ball size. It did not hold a charge longer than 10 minutes. The texture was softer but not worth buying for 20 minutes of fun 🙁
