Water Outlet Replacement Head

Product Introduction

This is a functional replacement part for aquarium water outlets specifically designed for an 18mm inner diameter. It can directly replace original or standard outlets to change water flow patterns, directions, or add functions (such as oxygenation, wave making), making it a practical accessory for DIY upgrading the water outflow effect of aquarium filtration systems. Its core value lies in providing users with a low-cost, highly customizable water flow solution.

Design Highlights

1. Precise Fit Interface: The outlet base is designed with a sufficiently deep socket joint, with an inner diameter precisely matching 18mm, ensuring a tight connection and preventing detachment and leakage.
2. Modular Function Expansion: Adopting a design concept where the base and functional head are separable. The base is responsible for connecting to the water pipe, while the functional heads (such as duckbill, rain shower, rotating head, etc.) can be replaced individually, achieving multiple functions from one base.
3. Optimized Water Flow Guiding Structure: The functional head typically has internal guide vanes or specific chamber structures that can disperse, redirect, or impart specific shapes (such as fan-shaped or rain shower-like) to the concentrated water flow output from the pump, reducing impact on fish and landscaping.
4. Convenient Installation and Maintenance: The overall structure is simple, with no small moving parts (or very few parts), making it easy for users to install, disassemble, and clean by hand, resulting in low maintenance costs.

Technical Parameters

• Core Adaptation Specification: Adapts to 18mm inner diameter, model outer diameter 17mm
• Connection Method: Socket-type, it is recommended to use pipe clamps or PTFE tape to ensure sealing.
• Main Material: Recommended for 3D printing with PETG or ABS resin, which offers good water durability and mechanical strength.
• Functional Head Types: Can be designed as duckbill, horn, rain shower (multi-hole), or rotating fan shape, etc.

Usage Scenarios

1. Water Flow Pattern Modification: Replace the original direct jet outlet, changing the water flow to a rain shower, fan, or duckbill style, suitable for planted tanks, small aquariums, and other scenarios requiring gentle water flow.
2. Increased Oxygenation Function: Designed with rain shower or Venturi principle, air is drawn in during water outflow to increase dissolved oxygen levels in the aquarium water, especially suitable for keeping high-oxygen demanding fish.
3. Adapting to Non-Standard Pipe Fittings: Provides a solution for filtration systems (such as SUNSUN 704B) that use 18mm water pipes but cannot find suitable original factory outlets.
4. DIY Filtration System Upgrade: Used to modify the outlet end of back filter, side filter, or self-made filtration systems to optimize water circulation efficiency
