The most fundamental material decision for inlet, vacuum and main-drain nozzles is stainless steel vs ABS plastic. Both are the right choice in certain scenarios — the difference shows up in budget, durability expectations and appearance.
| Criteria | Stainless Steel | ABS Plastic |
|---|---|---|
| Impact/crack resistance | High — can deform but low crack risk | Moderate — can crack under hard impact |
| Corrosion risk | Depends on grade (304/316) — low when correctly specified | None — plastic doesn't corrode |
| Aesthetics / premium look | Chrome/satin finish — premium appearance | Matte plastic finish — standard appearance |
| Price | Can be roughly 10-20x higher than ABS | The most economical option |
| Typical use case | Hotels, villas, public pools — premium/visible mounting points | Budget-focused projects, low-visibility technical points |
Which one should you choose?
For visible mounting points (eye-catching poolside nozzles/grilles) and projects where long-term durability is a priority, stainless steel — with the correct grade (304 or 316) — is the better investment.
For budget-constrained projects, low-visibility points, or applications that don't require stainless, quality UV-stabilized ABS plastic is a reasonable, economical alternative.
A mixed approach is also common: stainless at visible/premium points, ABS at technical/hidden points, optimizing total project cost.
