Pentair 1.25" Quad De Clamp Band Spring

The Pentair 1.25" Quad D.E. Clamp Band Spring (OEM Part #196013 / #196013Z) is a specialized structural safety component designed specifically for the heavy-duty metal tension clamp rings that seal the upper and lower tank halves of Pentair Quad D.E.® and select Clean & Clear Plus filtration systems. Fabricated from thick-gauge, high-tensile stainless steel, this 1.25-inch compression spring rides directly over the central T-bolt of the clamp assembly alongside the locking barrel nut. Its primary mechanical function is to regulate and distribute uniform physical tension around the fiberglass tank flange, flattening the main inner tank O-ring to establish an absolute watertight seal under high hydraulic operating pressures. It acts as a visual torque indicator for pool technicians: tightening the barrel nut until the spring coils fully compress together signifies that the correct closing force has been achieved, preventing over-tightening that could fracture the composite tank lip while ensuring the vessel cannot catastrophically separate during pump operation. Weighing approximately 0.30 to 0.40 pounds on its own, it typically carries a packaged shipping weight of 0.60 to 1.0 pound when packed in protective small parts padding or bubble envelopes to prevent thread degradation during transit.
