Hurricane Spa Jet body replacement kit for Hurricane Jets 125mm used on Spa Industries, Signature, Cyclone, Designer, Leisurite, Wilton, and more. They commonly break / leak at the small barb on the rear, due to excessive strain from the air tubes. It is best to order new jets when replacing these bodies. Originally were a lighter grey, and sometimes white.
New repair kits come with clear jet & air tubing. Photos may show the older braided hosing, which is no longer required.
Spa Jet Install Notes:
Remove old jet body
- Remove old jet body.
- Remove old silicone/gasket residue and clean + dry both sides of the shell (no oils/soap film) before refitting.
- You may need to be creative in removing old jet body.
Sealing
- Apply silicone sealant on the jet face and rear where it passes through the shell.
- Many techs remove any supplied gaskets and rely on silicone + correct nut tension (our preference).
- Tighten the nut evenly until sealed. Use some silicone sealant on the thread to lock it in place. Do not overtighten (can crack/distort the shell or fittings).
- Note there are no specific tools for this job, so be creative!
Hose / Plumbing
- PVC glue on male barbs only. Do not put PVC glue into the tube/hose (can create a glue plug).
- Use gentle heat (or hot water) to soften the hose so it slides onto barbs easier.
Wait at least several hours before testing.
This jet repair kit comes with:
- Hurricane Jet Body
- Hurricane Seal & Fittings
- Large Hose Tube Joiner

- Small Hose Tube

Used on spas manufactured by Spa Industries including Signature Spas, Cyclone Spas, Leisurite, Lanark, Heritage, Designer Spas, Wilton and others
Replacement Hurricane Jets
In plumbing, named sizes are not the actual measurements. A pipe called “50mm” or “2"” does not measure 50 mm across. Instead, it follows nominal sizing, an internationally-standardised naming system.
Use the Outside Diameter (OD) to check your pipe against fittings. Below is a quick reference for common spa & pool pipe sizes:
| Imperial Name | Metric Name | Pipe Diameter (OD) |
|---|---|---|
| 1" | 25 mm | ~33.4–33.7 mm |
| 1.5" | 40 mm | ~48.1–48.4 mm |
| 2" | 50 mm | ~60.2–60.8 mm |
| 2.5" | 65 mm | ~75.2–75.5 mm |
These are nominal sizes and are designed to fit matching fittings — not to measure exactly what their name suggests.
Understanding Plumbing Sizes & Nominal Measurements
Plumbing sizes can be confusing. PVC and many other pipe systems use nominal sizes—the size is a name, not the exact measured dimension. This convention is used across most pool and spa systems so that pipes and fittings remain compatible.
Why pipe sizes don’t match the measurements
The Nominal Pipe Size (NPS) system standardises pipe dimensions so that pipes, fittings, valves, and accessories interoperate. Plumbers work with these nominal names every day, but DIYers can be tripped up if they try to match by a tape-measure alone.
How to Measure Pipe Correctly
-
Pipe size is identified by:
- The pipe’s Outside Diameter (OD).
- The fitting’s Inside Diameter (ID) (socket opening).
- Pipe Class / Schedule (e.g., Class 9, 12, 18 or Sch 40) relates to wall thickness and therefore the Internal Diameter (ID) and pressure rating.
- The outside diameter of a fitting is not useful (wall thickness varies by manufacturer).
PVC Pressure Pipe AS/NZ 1477 Dimensions1:
Common nominal sizes with typical outside diameters and indicative inside diameters by class.
| Imperial Name | Metric Name | Outside Diameter (OD) |
|---|---|---|
| 1/2" | 15 mm | ~21.2–21.5 mm |
| 3/4" | 20 mm | ~26.6–26.9 mm |
| 1" | 25 mm | ~33.4–33.7 mm |
| 32 mm | ~42.1–42.4 mm | |
| 1.5" | 40 mm | ~48.1–48.4 mm |
| 2" | 50 mm | ~60.2–60.8 mm |
| 65 mm | ~75.2–75.5 mm | |
| 2.5" | ~73 mm |
- º Internal diameters vary slightly by manufacturer and class.
- 1 Not all pool/spa fittings match these dimensions exactly. Some do not follow Australian or international standards. Chinese spas may use proprietary fittings.
Hose & Tube Dimensions
Common flexible hose sizes used in pool/spa systems (approximate IDs).
| Imperial Name | Metric Name | Inside Diameter (ID) |
|---|---|---|
| 3/8" | 9–10 mm | ~9 mm |
| 3/4" | 19 mm | ~19 mm |
BSP – British Standard Pipe Thread Sizes
BSP thread names are also nominal. The thread OD will not equal the nominal name.
| BSP Thread Size Naming | Outside Diameter (mm / inch) | TPI |
|---|---|---|
| 1/16" BSP | 7.7 mm / 0.304" | 28 |
| 1/8" BSP | 9.7 mm / 0.383" | 28 |
| 1/4" BSP | 13.16 mm / 0.518" | 19 |
| 3/8" BSP | 16.66 mm / 0.656" | 19 |
| 1/2" BSP / 15 mm | 20.99 mm / 0.825" | 14 |
| 5/8" BSP | 22.99 mm / 0.902" | 14 |
| 3/4" BSP / 20 mm | 26.44 mm / 1.041" | 14 |
| 7/8" BSP | 30.20 mm / 1.189" | 14 |
| 1" BSP / 25 mm | 33.25 mm / 1.309" | 11 |
| 1-1/4" BSP | 41.91 mm / 1.650" | 11 |
| 1-1/2" BSP / 40 mm | 47.80 mm / 1.882" | 11 |
| 2" BSP / 50 mm | 59.61 mm / 2.347" | 11 |
| 2-1/4" BSP | 65.71 mm / 2.587" | 11 |
| 2-1/2" BSP | 75.18 mm / 2.960" | 11 |
| 3" BSP | 87.88 mm / 3.460" | 11 |
| 4" BSP | 113.03 mm / 4.450" | 11 |
