Filter Seam Sealing
The following reviews some of the filter seam sealing adhesive properties desired for rolled seams found in spin on fluid filters.
- 100% leak free seal
- Gap Filling
- Seamless Process (I couldn’t resist!)
- In Line QC Check
- Chemical Resistance
- Environmental Resistance
Spin on fluid filters (like automotive oil filters) have a rolled seam on the end where the can attaches to the nut plate. Anaerobic adhesive sealant provides a leak-free filter. Simply dispense the anaerobic adhesive sealant via an automated dispense system which is in line with the can roll process. Because the sealant is between metal with no contact with oxygen, the sealant cures. Thus, there is no additional line time required for dispensing or curing.
Additionally, products with high gap fill capability are available to allow for imperfections in the rolled seam. To ensure enough anaerobic adhesive sealant is dispensed for complete coverage, a sealant with fluorescing ability can be used, and the process can be viewed through automated fluorescent detection equipment.
Many spin on fluid filters are for automotive applications, so the ‘under the hood’ performance requirements, include resisting:
- A wide temperature range
- Various automotive fluids
- Water
- Salt water spray
