What the names mean
FEA15 is commonly used for a traditional fragrance crimp finish. A 15mm screw system uses a threaded fixation and may follow different geometry. The words “15mm” do not define the complete interface.
Crimp and screw compared
| Decision | FEA15 crimp | 15mm screw |
|---|---|---|
| Assembly | Requires controlled crimping equipment | Uses threaded application and torque control |
| Removal | Normally permanent | Can support removal and refill routes |
| Checks | Crimp diameter, height, seal and glass stress | Thread specification, torque, anti-loosening and seal |
| Components | FEA pump, collar and cap stack | Exact screw pump, collar and cap stack |
Compatibility checklist
Confirm the current bottle and pump drawings, ferrule or thread geometry, bore, assembly height, gasket, collar diameter, cap engagement, dip-tube cut and filled-product leakage test.
Sustainable screw-neck development
Industry work on SNI and CNI finishes is intended to preserve component appearance and support interchangeability in defined systems. That does not make unrelated nominal 15mm parts automatically interchangeable.
