Genuine Coxreels replacement swivel, 3/8 inch NPT with a 90 degree full flow fluid path and nitrile seals. Two versions, selected above: brass 433 for our blue reel, and 316 stainless 433-SS for our black reel. They are not interchangeable, so check which reel you have before you choose.
Go by the colour of your reel. It takes two seconds and it is the only thing you need to get right.
Choose 433 brass
Choose 433-SS stainless
Do not substitute one for the other. The brass 433 and the stainless 433-SS are separate parts and one will not stand in for the other. If you are not sure which reel you have, send us a photo before ordering and we will tell you which option to select.

Check your machine's pressure against the swivel, not just the reel. The brass 433 is rated to 3,000 PSI. The 100 Series reel itself is rated to 4,000, and plenty of professional pressure washers run above 3,000. A swivel is a pressurised rotating joint and it must never be the lowest rated part in your line. If your machine exceeds 3,000 PSI, the stainless 433-SS is the correct part, not the cheaper option.
Coxreels renamed the brass swivel. What was supplied as 1935 is now 433. Same brass 3/8 inch NPT swivel, same nitrile seals. If your paperwork, your parts list or the swivel on the reel says 1935, the brass option on this page is the replacement.
Everything else on a hose reel is static. The frame, the discs, the brake. The swivel is the only component that is pressurised and rotating at the same time, every time somebody pulls hose off or cranks it back on.
It also sits at the inlet, which is the lowest point, which is where water collects. In a detailing bay that water is rarely clean. It carries snow foam, wheel cleaner, iron remover and salt off customer cars.
Brass handles the pressure and the rotation without complaint. What wears it is the chemistry. The surface tarnishes, then pits, and a pitted sealing face goes through seals far faster than a smooth one. 316 is the marine grade stainless, and it holds a clean sealing surface in exactly the conditions that pit brass. That, plus the higher pressure rating, is what you are paying the difference for.
Pull the swivel, clean it and look at the sealing surface before you decide. If it is smooth, seals will fix it. If you can feel pitting with a fingernail, no seal is going to hold against that for long.
| Isolate and depressurise | Shut off the supply and pull the trigger to bleed the line before you touch the swivel. |
| No need to drop the reel | The Coxreels swivel design allows replacement with the reel still on its mount.Which is why boxing the swivel in behind hard plumbing is a mistake at install. |
| Use the right sealant | These are NPT tapered threads. Use thread sealant or PTFE tape rated for your pressure and keep it off the first thread so nothing ends up in the line. |
| Do not overtighten | NPT seals on the taper, not on torque. Overtightening is how bodies crack. |
| Pressure test | Bring the system up slowly and check for weeping before you put the reel back into service. |
| Check the rating | Confirm your machine sits inside the rating of the swivel you fitted, 3,000 PSI brass or 5,000 PSI stainless. |

Material, pressure rating, seal material, thread size and fluid path are the Coxreels published specifications for the 433 and 433-SS. Temperature range depends on the seal material fitted. The two swivels are not interchangeable. Confirm which reel you have before ordering, and confirm your machine's working pressure sits inside the rating of the swivel you select. Installation of pressurised fittings should be carried out by someone competent to do so.
