Small, but mighty
To keep your equipment running smoothly, sometimes it’s the littlest things that can really make a difference. When it comes to MicroBlasting equipment this little, but mighty thing is an O-ring. It’s a simple item that creates an reliable seal to protect your blaster from:
1) Getting abrasive getting where it shouldn’t and causing serious damage to your machine.
2) Losing tank pressure inhibiting blasting
O-rings are simple to inspect and easy to replace.
Depending on your blaster, you may have one or several O-rings that should be periodically checked for wear.
