ABSTRACT:
Improved apparatus and method for installing a filter sleeve in filtration apparatus is provided. In its basic form, the present invention uses a filter sleeve with a pre-installed end cap bonded to at least one of its ends. Through use of a bonding process such as sonic welding, the end cap and filter sleeve form a tight seal with one another which is durable and quite resistant to leakage. The end cap can be provided with receptacles to allow for ready interface with existing filtration apparatus, eliminating presently utilized mounting procedures which can be ineffective, burdensome, and time consuming. Additionally, improved method is also provided for securely sealing the opposite end of the filter sleeve.
