FAQ
Is the plug compatible with pressurized drain testing during production?
Yes-it maintains seal integrity under standard factory drain pressure tests (≤5 kPa). Not intended for high-pressure hydrostatic testing.
Can it be used on wall-mounted units?
No-this model is specifically designed for the larger drain ports of floor-standing indoor units. Wall units require smaller-diameter plugs.
Does the ABS body yellow or crack over time in sunlight?
The plug is for indoor use only. ABS is not UV-stabilized-prolonged direct sunlight may cause discoloration, but it won't affect sealing performance indoors.
What's the thread specification?
Standard metric thread M20×1.5 (matches most OEM drain ports). Custom threads available upon request.
