FAQs

Common questions answered.

Five of the questions we hear most often on carpark and street linemarking gear. Full knowledge base on our FAQ page.

  • Honda GX engine service parts?

    JetWave-spec air filter cartridges + air cleaner elements + oil filter cartridges + fuel filter assemblies for Honda GX160/GX200/GX340/GX390 engines on the JetWave Hornet + Senator + Executive + PMG range. Match the Honda GX service interval (typical 100 hour). Skipping engine service shortens engine life + voids warranty.

  • Why a Y-strainer on water inlet?

    Water inlet Y-strainer + In-Line Filter (80 mesh / 210 micron) protect the pump from supply-side debris. Critical on rural + bore + tank-fed water supply where particulate accumulates. Inspect monthly; clean at any pressure-drop indication. Skipping = pump damage + warranty void.

  • Which O-ring chemistry?

    Buna-N for general water + air. Viton for higher-temperature + chemical work. Match O-ring chemistry + size to the failed seal - using the wrong material causes swell + leak within hours. JetWave Replacement O-Ring + Brown Backup Ring covers most commercial pressure washer rebuilds.

  • Dowty bonded sealing washer - what is it?

    Dowty washer is a bonded steel + rubber sealing washer that seals the threaded face of high-pressure hose + fitting connections. Used between the male thread shoulder and the female face. Standard service item on JetWave commercial pressure washer threaded connections.

  • What connection types and thread standards are used with filters & o rings?

    Australian fluid handling equipment predominantly uses BSP (British Standard Pipe) threads in sizes from 1/4" to 3" BSP. Some imported equipment uses NPT (National Pipe Thread) — adapters are available but check thread type before connecting. Cam-lock fittings (Type A through F) are standard for quick-connect hose couplings on tanks and bowsers. Flanged connections (ANSI 150#, AS 4087 Table D/E) are used on larger installations. Always verify thread type, size and pressure rating before assembly to prevent cross-threading or leaks.
