PoolSupplyTown Spa Directional Flow Jet SP1419D
The PoolSupplyTown SP1419D is a directional hydrostream return jet fitting designed as a Hayward SP1419D replacement. It provides adjustable velocity and flow with a rotating 3/4″ eyeball opening.

Why selected: It mirrors the original SP1419D functionality with adjustable opening, enabling targeted water circulation. It’s a practical pick when you need a direct compatibility match and straightforward installation.
Limitations: Check actual pipe diameter compatibility before purchase to ensure slip or thread-match with your plumbing. Some installations may require basic pipe adaptation.
ATIE SP1421C Directional Hydrostream Jet Insider Fitting
The ATIE SP1421C Insider Fitting is a 5-pack option with a 1/2″ eyeball opening designed for 1-1/2″ slip connections. This inside-slip configuration fits Hayward SP1421C setups and provides adjustable jet direction for more balanced pool circulation. Best for those replacing multiple jets or outfitting a small to mid-sized pool with consistent flow across multiple return points.
Why selected: The 5-pack offers cost-effective replacement across several returns, reducing downtime during upgrades. Its inside-slip design minimizes external fittings.
Caution: Confirm that your piping is 1-1/2″ slip and that the eyeball size matches your desired flow control. The 1/2″ opening is smaller than some larger jets, which could influence flow volume.
Thinp Pool Jet Nozzles, 2 Pieces
The Thinp Jet Nozzles include two 3/4″ inlet fittings with 1-1/2″ MIP thread. They are designed to reintroduce clean filtered water and support proper pool circulation after filtration. Best for budget-conscious buyers seeking reliable ABS plastic jet replacements with straightforward installation.
Why selected: Good value for replacement projects requiring durable ABS materials and simple, direct installation. They cover common 3/4″ openings frequently used in pool returns.
Limitation: Being a basic replacement, they may lack some advanced adjustability found in higher-end jets. Ensure thread and opening sizes align with your existing fittings.
Drokenle Pool Jet Nozzles, 2 Pieces
The Drokenle set includes two 3/4″ opening return fittings with 1-1/2″ MIP thread. These ABS plastic jets are designed to deliver directional flow while withstanding pool chemicals and outdoor exposure. Best for pool owners who want dependable, mid-range performance at a reasonable price.
Why selected: Durable construction and a straightforward replacement option that aligns with common Hayward and other 1-1/2″ threaded systems.
Consideration: Ensure your installation space supports the 1-1/2″ MIP thread to avoid compatibility issues with slip-based connections.
ATIE 1-1/2″ Return Jet Fitting for Hayward SP1419B
This ATIE model features a 3/8″ eyeball opening with 1-1/2″ MIP threading, designed as a direct replacement for Hayward SP1419B. It allows precise velocity and flow control when installed in compatible pool spa systems. Best for users who need a smaller eyeball opening for more controlled returns.
Why selected: The small opening supports finer flow management, useful in smaller pools or precise spa water management scenarios.
Limitation: The 3/8″ opening may reduce overall flow in high-demand setups; pair with other high-flow returns if you need more volume.
PoolSupplyTown SP1419E Jet Fitting
The SP1419E model from PoolSupplyTown offers a 1″ opening with 1-1/2″ MIP thread, designed to replace Hayward SP1419E. It provides adjustable velocity and flow with a larger opening for greater circulation. Best for larger pools or spas needing higher flow along multiple returns.
Why selected: Larger opening supports increased water movement, which can improve overall turnover in bigger spaces or high-usage pools.
Note: Larger openings can alter balance with other jets; consider a mixed configuration to avoid uneven flow distribution.
PoolSupplyTown SP1419C 1/2″ Opening Jet
The SP1419C is a 1/2″ opening hydro stream return jet with 1-1/2″ MIP thread. It is designed to replace Hayward SP1419C and offers adjustable velocity and flow. Best for precise, low-flow jets in smaller or meticulously balanced pools and spas.
Why selected: The smaller opening is suitable for fine-tuning flow across a set of returns without overwhelming the system.
Limitation: With a smaller opening, overall flow is reduced; use with additional higher-flow jets to maintain turnover in larger spaces.
Buying Guide: How To Choose The Right Spa Jets For Your Pool
Key considerations help ensure you pick jets that fit your plumbing, deliver the right flow, and match your pool’s size and usage.
- Opening size and flow control: Larger openings move more water; smaller openings offer finer control. Match to pool size and desired turnover rate.
- Thread compatibility: Common options include 1-1/2″ MIP threads and 1-1/2″ slip fittings. Verify your existing piping and adaptors before buying.
- Eyeball design: Adjustable eyeball jets allow you to direct flow, which helps balance circulation around corners and steps.
- Material durability: ABS plastic is common and corrosion-resistant, suitable for outdoor pool environments. Check chemical compatibility and UV resistance.
- Replacement vs. upgrade: If replacing Hayward models, look for exact or compatible part numbers to simplify installation and preserve performance.
- Pool size and usage: Bigger pools or high-use spas typically need higher-flow jets or multiple return points to maintain water quality.
- Installation considerations: Some fittings are slip-in, others thread in. Plan for any plumbing modifications or sealants as needed.
Frequently Asked Questions
- What is a hydrostream return jet and why replace mine? A hydrostream return jet directs water back into the pool and can improve circulation and comfort when properly aimed and adjusted. Replacing worn or incompatible fittings helps maintain expected flow control.
- How do I know which opening size I need? Larger openings move more water; smaller openings provide finer control. Consider pool size, turnover goals, and existing jet configuration.
- Are slip fittings different from threaded fittings? Yes. Slip fittings slide into a pipe, while threaded fittings screw onto a pipe. Confirm your system’s connection type to avoid leaks.
- Can I mix jets from different brands? It’s possible but ensure thread type, opening size, and flow characteristics align to prevent imbalanced circulation.
- Do these jets require professional installation? Most domestic replacements are straightforward for a handy homeowner, but consult a professional if you’re unsure about your pool’s plumbing or warranty concerns.
- Will a larger opening increase cleaning effectiveness? Larger openings increase flow but may disrupt balance with other returns. Use mixed jet configurations to maintain even distribution.
