Remote Filter Heads
A range of bracketed filter heads which take the modern spin on oil filter cartridge and enables relocation of the oil filter.Suitable oil filter elements are available from many manufacturers, most of them have catalogues with full specifications. When choosing, the first requirement is that it should have a 3/4"UNF thread, 1"UNF if high oil flows are anticipated. The larger the oil filter the less the oil pressure drop so chose the largest that can be accommodated unless weight is a problem. Filter heads can be mounted in any attitude, but we suggest when choosing an oil filter that is to be fitted in other than an upright, filter below, position, it should have an anti-drain valve. No provision is made in our heads for filter relief valves, these are available built-in on some filter elements, they should be avoided if regular oil changing and gentle warm ups can be relied upon. Filter heads can be mounted in any attitude, but we suggest when choosing an oil filter that is to be fitted in other than an upright, filter below, position, it should have an anti-drain valve. We are always pleased to recommend a filter for any application. Direction of flows listed below are for filters as illustrated. (remember oil always flows down the outside of the filter and returns up the middle).
