Pentair 194988Z Quick Release Spring Replacement The Pentair 194988Z Quick Release Spring is a replacement clamp spring used on compatible Pentair, Purex, PacFab, and Nautilus stainless steel D.E. filter clamp assemblies. This spring is part of the filter clamp tightening hardware and works with the matching T-bolt and brass clamp nut to help secure the clamp band around the filter tank. If your original clamp spring is rusted, compressed, damaged, missing, or no longer helping the clamp tighten evenly, replacing it with the correct 194988Z spring can help restore smoother opening and closing of the filter clamp hardware. Why Buy the Pentair 194988Z Quick Release Spring? Replacement quick release spring for compatible Pentair/Purex/PacFab stainless D.E. filter clamp hardware Commonly used on legacy Nautilus / NS-style clamp assemblies Helps refresh worn clamp tightening hardware when the original spring is weak, rusted, or damaged Pairs with the correct brass clamp nut and stainless T-bolt Practical repair part for older filters where complete clamp assemblies may no longer be available Product Details Brand Pentair Manufacturer Part Number 194988Z Product Type Filter Clamp Quick Release Spring Application Compatible older Pentair, Purex, PacFab, and Nautilus-style stainless D.E. filter clamp assemblies Common Repair Use Clamp spring replacement for worn or hard-to-tighten filter clamp hardware What Does the 194988Z Spring Do? The quick release spring is part of the clamp tightening system on compatible stainless D.E. filter clamps. It works with the T-bolt, washers, and brass clamp nut to help apply controlled tension to the clamp band as the hardware is tightened. When the spring is worn out, corroded, or compressed, the clamp can become harder to tighten, harder to loosen, or less consistent when securing the filter tank. Replacing the spring can help restore smoother clamp operation when the rest of the clamp band is still in usable condition. ATB Fitment Note The Pentair 194988Z spring should be matched with the correct T-bolt and brass clamp nut for your specific clamp assembly. On older Nautilus / NS-style stainless filter clamps, both tightening points may use this spring. If both sides are worn, two springs may be needed. When Should This Spring Be Replaced? The original clamp spring is rusted or heavily corroded The spring is compressed, cracked, or damaged The clamp is difficult to open or close during filter service The clamp nut no longer tensions smoothly You are refreshing the tightening hardware on an older stainless D.E. filter clamp Common Repair Pairing On compatible legacy stainless D.E. filter clamp setups, the Pentair 194988Z Quick Release Spring is commonly replaced along with the matching brass clamp nut and stainless T-bolt. If both sides of the clamp hardware are worn, you may need two springs, two brass nuts, and two T-bolts to refresh both tightening points. Important: This listing is for the quick release spring only. It does not include the T-bolt, brass clamp nut, washers, clamp band, or complete clamp assembly unless those parts are purchased separately.
