CR 03 12

All Star CNC CR 03 12 Round Vacuum Gasketing — Frequently Asked Questions

1. What is CR 03 12 Round Vacuum Gasketing?

CR 03 12 is a round-profile vacuum gasket designed for CNC router spoilboards and dedicated vacuum fixtures. It installs into routed round channels to create a secure air-tight seal and improve vacuum hold-down strength.

2. What do the numbers “03 12” represent?

“03” indicates approximately a 3/32″ (0.093″) height profile, and “12” indicates a 1/8″ (0.125″) diameter round gasket configuration.

3. What does “CR” designate?

CR identifies a round-profile (cylindrical) gasket style commonly used in CNC vacuum tables with routed round channels.

4. When should I use a 1/8″ diameter round gasket?

A 1/8″ diameter gasket is typically used in smaller routed round channels or detailed vacuum fixtures requiring a narrower sealing profile.

5. How does round gasketing differ from flat in-board gasket?

Round gasket provides a raised compression surface that seals within round-channel routing, while flat in-board gasket is designed for rectangular grooves.

6. What CNC machines is CR 03 12 compatible with?

It is compatible with CNC routers and vacuum tables that use routed round-channel grid systems sized for 1/8″ gasket profiles.

7. What materials benefit from improved vacuum sealing?

MDF, plywood, hardwood panels, plastics, aluminum composite panels, and other sheet goods benefit from improved vacuum hold and reduced part movement.

8. Is CR 03 12 adhesive-backed?

Yes. The gasket includes adhesive on one side for easy installation into routed round channels.

9. How long is each roll?

Standard rolls typically contain approximately 164 feet of gasket material.

10. Does round gasket improve hold-down strength?

Yes. Proper installation improves vacuum zone isolation and increases suction strength at the part location.

11. Can this gasket be used in custom CNC fixtures?

Yes. It is commonly used in dedicated fixtures where precise and repeatable vacuum sealing is required.

12. Does it improve machining accuracy?

Yes. Stronger vacuum isolation reduces vibration and part shifting during CNC cutting operations.

13. Can it reduce the need for tabs?

Yes. Improved vacuum performance can reduce or eliminate the need for mechanical tabs or hold-down devices.

14. Is CR 03 12 suitable for nested-based CNC routers?

Yes. Nested-based CNC routers benefit from proper vacuum sealing to maintain part stability, especially with smaller components.

15. How do I confirm this size is correct for my vacuum table?

Measure the diameter of your routed round channels. The gasket should fit snugly without excessive compression or looseness.

16. Does smaller diameter gasket require less vacuum power?

Smaller gasket profiles typically require less compression force, making them suitable for lighter-duty vacuum systems.

17. Is this gasket reusable?

Once installed, it remains in place until wear or compression fatigue reduces performance. Replacement is recommended when sealing effectiveness declines.

18. Are other round gasket sizes available?

Yes. All Star CNC offers multiple round gasket diameters and profiles to match various CNC vacuum table configurations.
