Easy install, just place over closet bend, position ring and tighten bolts securely. Notched and slotted, 4 bolts for even clamping around pipe. Corrosion resistant 304 stainless steel bolts. Neoprene gasket meets ASTM C564. UPC, IAPMO approved (CF4 3x2 and CF4 4x2). Sits level on floor, so drain pipe can be cut flush. Metal ring provides added strength and cracking resistance to the flange and can be rotated to allow precise alignment of bolts and screws. Solvent welds inside 4" or over 3" Schedule 40.

Weld neck Flanges are drilled (machined) with the wall thickness of the flange having the same dimensions of the matching pipe. The lighter the pipe is, the larger the bore, conversely, the heavier the pipe, the small the bore. They are normally used for high-pressure, cold or hot temperature. Flanges 1/2" to 24" and up to 450 lbs to BS10 Table D & Table E, BS Table F & Table H, BS Table J & Table K. We can also manufacture in different shapes and sizes depending upon your purpose. Flanges are confined to special applications. Their chief merit lies in the fact that they can be assembled without welding this explains their use in extremely high pressure services, particularly at or near atmospheric temperature, where alloy steel is essential for strength and where the necessary post weld heat treatment is impractical. flanges are unsuited for conditions involving temperature or bending stresses of any magnitude, particularly under cyclic conditions.
