Replacement Cartridge

A:  I am sorry but you can’t do it definitively by crossing replacement cartridges to other replacement cartridges, as some will be interchangeable in some situations and not in others. You need to start by identifying the brand and model number of the filter housing, then you can ask if a specific replacement filter will work in that housing. For example, sometimes certain spark plugs will both work in one car but in another car one of them won’t be suitable. You really need to start with what model car and engine do you have and then look for an appropriate plug. As a plumber I have learned this the hard way on a job that ended up with a slow oil leak. In that situation the person converted to biofuel which is extremely corrosive and requires a special gasket.

A:  No this replacement filter is for an FB4 filter housing made be FulFlo. The model you reference, 1A-25 refers to a housing made by General. It would typically take a 1A-30 replacement cartridge, Home Depot SKU 202312942. There are other specialty cartridges made for that housing but in my experience the 1A-30 is the most common used for home heating applications.

A:  Sid Harvey’s is a supply house chain, they do not manufacture filters. The product you reference is a private label filter produced for them by a true filter manufacturer. I believe it is made for them by Mitco. I do not believe this filter to be appropriate replacement. And unfortunately I do not find anything on the Sid Harvey’s web site indicating what other cartridges can be used. So unfortunately I cannot give you a definitive alternative.

A:  I am sorry but can’t give you a definitive yes or no. Because it really depends on what specific filter housing you have installed in your system. I don’t want to lead you in the wrong direction. F10-8 is a Westwood brand part number. It fits in a number of different General, Westwood, Mitco and assorted private label filter housings. RF4B is a General brand model number. It is designed to fit a number of their fulflo housings. There is some overlap but not across all housings. The best way to approach this is to identify your filter housing and then see what filter options you have you have for that housing. Then depending on the type of fuel select the correct filter. For example bio heat fuel has very unique corrosive properties not present in conventional home heating oil. So when I am dealing with a customer that burns bio fuels, I identify the housing. And I select a bio fuel approved filter that is compatible with that housing.
