ABSTRACT:
An improved method of attachment of a pH or p sensor in the recirculation/filtration line for a pool or spa or for forming a T-connection between any two pipes comprises a saddle-clamp modified with an aperture to receive the shank of the sensor with an O-ring and a thinner, harder constricting ring surrounding the O-ring. When the saddle clamp is tightened, the constricting ring forces the O-ring toward the aperture while preventing excessive flattening of the O-ring.
