The tubing network connects your vacuum source to every collection point in your facility. The material, gauge, and diameter of that network directly affect suction performance, system longevity, and operator safety. At American Vacuum Company, we supply industrial central vacuum tubing in sizes from 1-1/2" OD through 14" OD, with central vacuum fittings available in belled (flared) or straight-end configurations. Since 1910, we have installed over 500,000 industrial vacuum systems across the United States.
We stock central vacuum tubing in carbon steel (1006-1010 ERW), zinc-coated (galvanized), stainless steel (304 alloy), and aluminum (6061/6063 extruded). We do not recommend PVC for industrial applications because it cannot be effectively grounded, creates dangerous static electricity buildup when conveying dust, and lacks the wear resistance that production environments demand.
All of our industrial central vacuum systems utilize industrial cental vacuum tube & fittings. Our central vaccum pipe & fittings are available in the following materials:
- Carbon
- Zinc
- Aluminum
- Stainless Steel
Industrial Central Vacuum Pipe gauges available:
- 11 Gauge
- 14 Gauge
- 16 Gauge
- Schedule 40
- Schedule 80 pipe
Frequently Asked Questions
Why does American Vacuum recommend metal tubing instead of PVC?
PVC is non-conductive, which means static charges accumulate on pipe walls with no effective path to ground. In industrial environments where dust in any form generates static electricity, this creates a real safety hazard. Metal tubing can be properly grounded and bonded to dissipate charges safely. PVC also has poor wear resistance and short-radius elbows that restrict airflow and cause material buildup at joints.
Can central vacuum tubing be added to an existing system?
Yes. Central vacuum systems are modular, and additional drops or branches can be added to expand coverage. The key is confirming that the vacuum producer and filtration system have sufficient capacity to support the new collection points without reducing suction at existing drops. Our team can evaluate your current system and design an expansion that maintains performance across the full network.
What is the difference between belled-end and straight-end fittings?
Belled (flared) end fittings have one slightly enlarged end that accepts a straight section of tubing, creating a lap joint. Straight-end fittings have a uniform outside diameter on both ends and require a separate coupling to join sections. Both create reliable connections when properly installed, and the choice depends on installation preferences and joining method.
