Dealing with Pipe Variances Internal-fit PVC fittings, accessories and couplers attach to the inside diameter of Schedule 40 PVC pipe. ASTM standards allow for a larger variance in the inside diameter of PVC pipe from manufacturers and often times the inner diameter may be too large, or even too small to accept the internal-fit fitting or accessory.
