Proper handling and installation of liquid spin-on filters is essential. Here are some simple, effective tips to help you get the job done right and minimise the risk of operational challenges.

Storing and Handling Filters on Site

Proper storage helps maintain filter integrity and prevents contamination before installation:

  • Keep filters in their original packaging, stored in a cool, dry, and clean environment.
  • Handle all filters with care to avoid damage.
  • If the packaging is dusty or dirty, take care not to transfer contaminants onto the filter.
  • Follow a first-in, first-out approach—use older stock first when possible.

Don’t Use Damaged Filters

A dented or damaged filter has been compromised and may fail in service:

  • Before installation, inspect the filter inside and out for damage or contamination.
  • Never install a filter that shows visible damage.
  • Replace filters damaged in service—don’t take risks with your equipment or safety 

Installation Do’s and Don’ts

When installing liquid spin-on filters, keep these best practices in mind:          

  • The old filter will be tight and require a wrench for removal
  • Clean the filter head with a lint-free cloth, and confirm the old gasket has been removed
  • An overtightened filter may unwind the spigot; check that the spigot is secure in the head
  • Inspect the spigot thread for damage and condition
  • Visually confirm that the new and old filters are the same part number or product.
  • Inspect the new filter for damage and internal contamination.
  • Confirm that the O ring is correctly located and lubricate with clean fluid or engine oil
  • Never lubricate the gasket with grease, rubber grease, dispersants, lanolin or dirty fluids 
  • Avoid priming or prefilling filters. Generally, (not always) a liquid filter's flow path has the dirty fluid entering via the small outer holes and the clean fluid leaves through the large centre hole. If you must prefill a filter, the liquid should be pre-cleaned or take care to prefill the filter through the small outer holes. 
  • Spin the filter on by hand until the O ring or gasket contacts the filter head.
  • The filter-can provides tensioning requirements: gasket contact + how many turns. Your filters fitting instructions may include + ½ + ¾ + 1 etc turns past gasket contact.       
  • Tighter is not better, install filters by hand only, as wrenches may damage the filter
  • Refill fluid to the correct level, run engine and check for leaks, top up fluids if required  
  • Comply with local, state, and federal regulations for the correct disposal of used filters
