Verify Series and Connection Type

Confirm the existing installation uses a 3/4 in FNPT pipe connection and a 0.25 in bolt hole pattern. Check that the system matches the listed 110 or 2400 series family and the noted manufacturer model numbers.

Cast Iron Durability Under Load

Cast iron construction resists deformation and corrosion during continuous service in non-potable drainage systems. The two-hole mounting pattern distributes mechanical stress evenly across the flange face.

Questions about this item

Does the PK2 pack include bolts for the two mounting holes, or must I supply them separately?

The package contains two cast-iron flanges with 0.25 in bolt holes and FNPT threads for 3/4 in pipe. Mounting bolts are not included and must be purchased separately.

How do I decide between the 110 and 2400 series compatibility listings?

Choose based on the pump or valve model you are connecting. The flange fits Taco models 007e, 110-113, 2400-10-3P, 2400-20-3P, 2400-45, 2400-50-3P, HEC-2, VR1816, VR3452 and VT2218. Match your equipment model number to this list.

What does the 0.25 in bolt-hole size mean when I install the flange on a 3/4 in FNPT pipe?

Each flange has two mounting holes drilled to 0.25 in diameter. You will need bolts of that shank size to secure the flange to the mating surface after threading the 3/4 in FNPT connection onto the pipe.
