King Technology New Water #407C Chlorine Cycler Pac
Drop it in. Never touch chlorine.
The King Technology New Water #407C Chlorine Cycler Pac (MPN 01-03-4613, SKU PST-01034613) is a pre-filled 6.16 lb chlorine cartridge that drops straight into your New Water in-ground Cycler with no measuring, no lifting a chlorine bucket, and no cloud of chlorine fumes. Inside the pac, New Water's erosion-control design wets only a small slice of the chlorine at a time, so output stays uniform and each pac lasts far longer than loose tablets in an ordinary feeder. Set the Cycler dial to match your pool and the system meters out a steady low level of sanitizer on its own.
Why PST Customers Pick This
Pre-Filled, No Handling
The 6.16 lb chlorine charge is sealed inside the pac at the factory. You drop the pac into the Cycler and snap the lid, no scooping tablets, no measuring, no chlorine fumes in your face.
Erosion-Control Output
New Water's erosion design exposes only a small amount of chlorine to water at once. Output stays steady and uniform instead of spiking, and one pac lasts noticeably longer than the same weight of loose tabs.
9-Setting Adjustability
The Cycler dial gives you 9 settings so you can dial output up during a heat wave or heavy bather load and back down when the pool is quiet, matching sanitizer to real demand.
Sized For In-Ground Pools
The #407C pac is rated for in-ground pools from roughly 7,000 to 25,000 gallons on the New Water Cycler, giving reliable sanitizer coverage across most residential inground sizes.
True Drop-In Fit
Keyed to seat only one way, the pac aligns into New Water Cycler models 400 and 430 (and series 600 / Pool Frog XL Pro 5400 systems) so replacement takes seconds with no tools.
Genuine King Technology
This is the authentic New Water #407C pac, part 01-03-4613, built to King Technology spec so it seats, seals, and erodes exactly the way your Cycler was engineered to run.
Chemical Safety
This pac contains Trichloro-s-Triazinetrione (trichlor), a strong oxidizer. Never mix it with any other chlorine, chemical, or an old pac of a different type, mixing chlorinated products can trigger a fire, explosion, or toxic gas release. Handle the pac in a well-ventilated area, keep it dry until it goes in the Cycler, wear eye protection, wash hands after handling, and store it sealed away from children, pets, and heat. Always shut the pump off and relieve system pressure before you open the Cycler lid to swap a pac.

Frequently Asked Questions
Which New Water Cyclers does the #407C pac fit?
The #407C (01-03-4613) is the in-ground chlorine pac for the New Water Cycler models 400 and 430, and it is also compatible with the 600 series and the Pool Frog XL Pro 5400 systems. If your in-ground Cycler takes the taller inground pac, this is the correct replacement. Above-ground Cyclers use a different, smaller pac, so confirm your unit is an in-ground model first.
How is this different from the smaller above-ground pac?
The #407C is the larger 6.16 lb in-ground pac rated for pools up to about 25,000 gallons. The above-ground New Water pac (a different part number) holds roughly 4.16 lb and is sized for smaller above-ground pools. They are not interchangeable, using the wrong pac means it either will not seat correctly or will not sanitize the volume of water you have.
How long does one pac last?
Most pools get 2 to 4 weeks from a single #407C pac. Actual life depends on your pool size, pump run time, bather load, water temperature, and where you set the Cycler dial. Hot weather and heavy use burn through chlorine faster, so check your pac at each water test and replace it before it runs empty to avoid a sanitizer gap.
Can I install this pac myself?
Yes. Shut the pump off and relieve system pressure first, then open the Cycler lid, lift out the spent pac, drop the new #407C in until it keys into place, and reseat the lid. Set the dial to match your pool and restart the pump. No tools and no loose chemical handling are required, but always wear eye protection and wash your hands afterward.
Does the pac contain minerals too, or just chlorine?
The #407C is a chlorine-only pac. On New Water systems that also run a separate mineral cartridge, the minerals do the heavy lifting and this chlorine pac supplements sanitation, King Technology notes that pairing minerals with the Cycler can cut chlorine use by up to 50%. On its own, the #407C simply supplies steady erosion-controlled chlorine to your in-ground pool.

Let customers speak for us
The only place I could find with the part I needed. Delivery was fast and the price was great. Best pool supply store on the web.
Part was easy to find and arrived a couple of days earlier than originally scheduled.
The ceramic spindle in the center of the original impellor broke. Replacement with this part was super easy and pump performs like new.
Ease of purchase replacement part took care of the problem
Received the correct replacement part. Not a real tough job. Part works great!
Better than the PA version at fraction of the cost.
Just what I needed for my syllent pump that comes with no Jacuzzi pump coupler. Do need a 1 1/2x1 1/4 reducer but everything will work out just fine..
This product seems to work great so far! I’m only two days in but the leak around my steps seems to have been completely stopped after applying this
All went well. Fast shipping AAAAAAAAAAA++++++++++++
Our pool and spa are over 25 yrs old. When the spa air button stopped working, we found that it was no longer avaliable. We did some online searching and found that this was a good replacement option and found it on the PST Pool Supplies website. We ordered it and once it arrived, we were very happy that we were able to install it and it worked fine.
Exact replacement Weir door that fit perfectly! Solved the problem of my old worn out doors!
