SEE REPLACEMENT PART: OBSOLETE

Pentair EQW300/EQ1500 Diffuser 1/4"-20 x 1-3/4" Bolt is intended for pool and spa pump service where a worn, cracked, missing, or poorly fitting internal component is affecting water movement, priming, or system efficiency. This replacement part is useful during pump rebuilds, leak repairs, and performance restorations because it helps keep the correct relationship between the motor, impeller, diffuser, volute, basket, or seal area depending on the specific assembly. When working on older Pentair, PacFab, Sta-Rite, or related pump systems, matching the part number and horsepower/application details is especially important because similar looking parts may not interchange correctly. Use this item when the existing component shows signs of fatigue, distortion, broken mounting points, stripped hardware contact, or reduced hydraulic performance.

For this specific item, use part number 356797 as the primary reference when checking fitment. The vendor listed for this product is Pentair Pool Products, and the category is Pump Parts, which helps identify the most likely equipment area but should not replace direct comparison with the original part. If the old part is still available, compare connection points, mounting locations, color or finish, molded markings, and any printed service numbers before installing the replacement.
