Pipe Support and Jet Valve 637R/12363 – for Above Ground Pools – Mounting Accessory with Black Cap Included

This is a modular component for above-ground pool recirculation systems, typically consisting of a pipe support and an adjustable air jet valve (nozzle), part numbers 637R and 12363. It is usually installed at the return inlet, inside the pool wall. One end is connected to the filter pump's water inlet via a flexible or rigid hose, while the other end is a nozzle fixed to the wall. The air jet valve is designed to allow the user to manually rotate its ball joint, precisely changing the direction and angle of the return water flow to optimize water circulation. By adjusting the direction of the air jet valve, a specific water flow is generated, pushing floating debris (leaves, dust, etc.) towards the skimmer and thus improving skimming efficiency. This flow also promotes vertical water circulation, eliminating areas of stagnant water caused by temperature fluctuations and uneven chemical distribution. The pipe support securely attaches the assembly to the pool wall, resisting impacts from the current. When the original air jet valve is blocked by scale and can no longer be adjusted, or the pipe support breaks due to age, using a 637R 12363 replacement part is the ideal solution. It restores precise control of the return water flow and direction, and is an effective way to optimize your pool water quality and improve cleaning efficiency, allowing your above-ground pool water circulation system to regain optimal control of the outlet point.
