PVC Hoses
PVC hose options for hot tub and swim spa plumbing, selected around your sizes, layout and connection requirements.
Explore the options.
Start with the application and the product direction you want to explore.
Match an existing hose
Start with the current dimensions, construction, appearance and application. A cut-end photograph and connection measurements can help.
Review an alternative
Discuss which details need to remain the same and whether construction, flexibility or presentation can change.
What a hose enquiry must state.
Use the following details to define a proposal around your application.
Dimensions
Internal and external diameter, wall construction and any dimensional tolerances in your specification. For the proposed hose, confirm actual inside and outside diameters, wall thickness and mating fitting dimensions from a measured sample or drawing.
Construction and flexibility
Reinforcement, bend requirements and how the hose needs to route through the assembly.
Connections
Fitting dimensions and the proposed joining method for the installation.
Operating requirements
The temperatures, pressures, water treatment conditions and applicable requirements defined for your system.
How a hose reference is read.
Hose enquiries are worked from four measurements plus how the hose is actually routed on the unit.
What to have ready
- Inside diameter where the connection sits
- Outside diameter across the wall
- Overall length, and whether it is measured fitted
- Connection type at each end
- Bend radius or how tightly the hose turns in place
- Where it is used: suction, return, jet feed or drainage
Configuration, considered together.
Share the lengths, colour or finish preferences, packing requirements and any identification or marking needed for your purchase. Options need supplier confirmation for the hose concerned.
What to photograph at each end.
Photograph each end straight on, with the fitting square to the camera and the bore visible.
Add one shot across the fitting with a rule alongside it, so the thread or spigot can be measured.

Reference data
Bore, wall and end fittings.
Two tables sit behind every PVC hose quotation: the values that decide whether a replacement will fit, and the references our customers already buy against. Send whichever you have and we check the rest.
| Field | What we confirm |
|---|---|
| Inside diameter | Bore of the hose, which sets the flow it can carry |
| Outside diameter | Outside measurement over the wall |
| Wall thickness | Wall between bore and outside, which affects pressure and bend |
| Working pressure | Pressure the hose is rated to work at |
| Bend radius | Tightest bend the hose takes without kinking |
| End fittings | Barbed, threaded or clamped connections |
| Temperature range | Range the hose is rated for in service |
| Length per coil | Coil length supplied |
| Reference system | Why it helps |
|---|---|
| Spa brand and model | Places the hose in a known plumbing layout |
| Fitting and thread at each end | Decides the end preparation and clamps |
| Measured bore and outside diameter | Confirms the size when the marking has worn off |
| Route and bend | Shows whether the hose has to turn tightly |
Values are confirmed per enquiry rather than published as a fixed list, because the bore, wall and fittings are quoted together.
Questions about PVC hoses.
Can you match a hose we already buy?
Send the current hose, its bore and wall, or the fitting at each end; the proposal is built to those measurements and the route it has to take.
Can appearance confirm the right hose?
No. Dimensions, construction, joining method and operating requirements also need to be checked.
Is the inside diameter enough to order a hose?
No. Outside diameter, wall thickness, working pressure and the fittings at each end are also needed.
How is the size confirmed when the marking has worn off?
The bore and the outside diameter are measured at both ends; the wall thickness follows from the two readings.
Which end fittings can be supplied?
Barbed, threaded and clamped arrangements are quoted; the thread and tailpiece are confirmed from the existing plumbing.
Can the hose be supplied in a specific coil length?
Coil length is quoted per enquiry, together with the bend radius the route needs.
