CR 03 25

All Star CNC CR 03 25 Round Vacuum Gasketing — Frequently Asked Questions

1. What is CR 03 25 Round Vacuum Gasketing?

CR 03 25 is a round-profile vacuum gasket designed for CNC router spoilboards and dedicated vacuum fixtures. It installs into routed round channels to create a reliable air-tight seal and improve hold-down strength.

2. What do the numbers “03 25” represent?

“03” indicates approximately a 3/32″ (0.093″) height profile, and “25” indicates a 1/4″ (0.250″) diameter round gasket configuration.

3. What does “CR” designate?

CR designates a round-profile (cylindrical) gasket style used in CNC vacuum tables designed with round-channel routing.

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

A 1/4″ diameter gasket is typically selected for CNC vacuum tables with 1/4″ routed round channels requiring moderate sealing surface and compression.

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

Round gasket provides a raised compression seal within round-channel grooves, while flat in-board gasket is designed for rectangular routed channels.

6. What CNC machines is CR 03 25 compatible with?

It is compatible with CNC routers and vacuum tables that use routed round-channel grid systems sized for 1/4″ gasket profiles.

7. What materials benefit from this gasket?

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

8. Is CR 03 25 adhesive-backed?

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

9. How long is each roll?

Standard rolls typically contain approximately 164 feet of gasket material.

10. Does round gasketing improve vacuum performance?

Yes. Proper installation improves vacuum zone isolation, increasing suction strength and reducing air leakage.

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

Yes. It is commonly used in dedicated fixtures requiring consistent and repeatable vacuum sealing.

12. Does it improve machining accuracy?

Yes. Enhanced vacuum hold reduces vibration and part shifting during CNC cutting operations.

13. Can it reduce the need for mechanical clamps or tabs?

Yes. Improved vacuum sealing often reduces or eliminates the need for mechanical hold-down devices.

14. Is CR 03 25 suitable for nested-based CNC routers?

Yes. Nested-based CNC routers benefit from strong vacuum isolation to maintain stability of smaller nested 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 securely without excessive compression or looseness.

16. Does a 1/4″ diameter provide stronger sealing than smaller profiles?

Yes. A larger diameter increases compression surface area, which can enhance vacuum isolation when matched to appropriate vacuum pump capacity.

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 designs.
