The best spin-on filter head depends on your fuel system’s connection size, required filtration, and flow needs. For a 3/4-inch setup, the DICMIC assembly is a complete option, while the HengShine offers a stated 10-micron rating. For 1-inch NPT connections, ATRACYPART and Dtomi list 25 GPM flow capacity and 30-micron filtration. The Fill-Rite kit is a choice for buyers seeking a hydrosorb filter assembly with installation fittings.

DICMIC 1200KTF7018 Fuel Filter Assembly
This kit pairs a spin-on particulate filter with a 1200KTG9075 filter head, a 3/4-inch ST elbow, and a 3/4-by-7-inch nipple. The listed applications include several FR transfer pump models, including FR112, FR1210G, FR610G, FR700, FR702R, FR701, and FR112C.
Best for: Buyers with a listed compatible pump who want the head and common connection fittings together. The product information states it can filter diesel, biodiesel blends up to B20, gasoline, gasohol up to E15, and kerosene.
Limitation: The supplied details do not state a micron rating or maximum pressure. Confirm those requirements and the pump connection before ordering.
ATRACYPART 1-Inch NPT Filter Kit
The kit includes a cast-aluminum 1-inch NPT filter head and a spin-on particulate filter. Its listed specifications are 25 GPM flow, a maximum pressure of 50 PSI, and 30-micron filtration. The product is described for construction and agricultural applications where fuel may contain dirt, silt, or corrosion particles.
Best for: Buyers whose system uses 1-inch NPT connections and needs the stated 25 GPM flow capacity. It provides a complete head-and-filter combination rather than a filter head alone.
Limitation: The 30-micron rating is coarser than the 10-micron ratings listed for some alternatives. Check the equipment’s filtration requirements before choosing it.
HengShine 1200KTF7018 10-Micron Assembly
This assembly includes a 1200KTG9075 head and a filter designed for 10-micron filtration. HengShine lists compatibility with FR152, FR112, FR1210G, FR610G, FR700, FR701, FR702R, and FR112C transfer pump systems. Specifications include flow up to 25 GPM, maximum working pressure of 50 PSI, and 3/4-inch NPT connections.
Best for: Buyers looking for a finer stated particulate rating than a 30-micron filter, provided the 3/4-inch connection and listed pump application match.
Limitation: The listing advises checking the model number and connection size. Do not assume compatibility based on appearance alone.
Fill-Rite 1210KTF7019 Hydrosorb Kit
This complete kit includes an F1810HM0 filter, a 1200KTG9075 head, a 3/4-inch elbow, and two pipe nipples. The product name specifies an 18 GPM, 10-micron hydrosorb filter. Fill-Rite describes the filter as helping protect equipment from dirt, rust, microbial growth, and water.
Best for: Buyers who want a hydrosorb filter kit with fittings included and whose system can use the stated 18 GPM capacity.
Limitation: Its listed flow is lower than the 25 GPM options in this comparison. Fill-Rite recommends changing filters every six months, so routine replacement is part of ownership.
Dtomi 1-Inch NPT Spin-On Filter
Dtomi lists a cast-aluminum filter head and spin-on cartridge with 1 1/2-inch-16 UNF cartridge threads. The assembly has a 1-inch NPT connection size, a 25 GPM flow rate, a maximum pressure of 50 PSI, and a 30-micron particulate rating. The listed fuels are gasoline, diesel, and kerosene.
Best for: Buyers fitting mobile, portable, or stationary transfer-pump tank setups that require the specified 1-inch NPT connections and 30-micron filtration.
Limitation: The 30-micron rating may not meet systems that require finer filtration. Verify fuel type and connection details for the intended installation.
Buying Guide: How To Choose A Spin-On Filter Head
Which connection size does your system need?
Match the filter head’s connection size and thread type to the pump and plumbing. The products here include 3/4-inch NPT assemblies and 1-inch NPT kits. These sizes are not interchangeable without suitable plumbing changes. Check the equipment documentation and the existing head before buying.
What filtration rating should you choose?
A micron rating indicates the size of particles the filter is designed to capture. The listed 10-micron options offer a finer stated rating than the 30-micron options. Choose according to the pump or equipment requirements rather than assuming that the finest rating is suitable for every system.
How much flow capacity is required?
Compare the filter’s listed flow with the transfer system’s expected demand. Several options list up to 25 GPM, while the Fill-Rite kit specifies 18 GPM. Also check the maximum pressure where provided; the ATRACYPART, HengShine, and Dtomi listings specify a 50 PSI limit.
Do you need the head and fittings included?
A complete assembly can simplify sourcing, but included fittings still need to match the installation. The DICMIC and Fill-Rite kits list elbows and nipples; the ATRACYPART and Dtomi products list a head and spin-on filter. Confirm what comes in the package before purchase.
Frequently Asked Questions
Is a spin-on filter head the same as a spin-on filter?
No. The head mounts to the fuel system and provides the filter connection. The spin-on filter is the replaceable cartridge. Some products include both components as an assembly.
Can I use a 30-micron filter instead of a 10-micron filter?
Only if the pump and equipment requirements allow it. The ratings differ, so check the manufacturer’s specified filtration needs before selecting a replacement.
Do these products fit every fuel transfer pump?
No. Compatibility depends on the pump model, connection size, thread type, fuel, flow, and pressure. Verify these details against the product specifications and equipment documentation.
How often should a spin-on fuel filter be replaced?
Replacement timing depends on the filter and operating conditions. The Fill-Rite listing recommends changing its filters every six months; follow the guidance for the specific filter and system.
