Multiquip APRD27836 1-1/2" NPT Black Steel Cap

The Multiquip APRD27836 is a genuine OEM 1-1/2" NPT Black Steel Cap designed for AP6 and AP8 series water pumps. As a direct Multiquip OEM part, it is manufactured to the same specifications as the original component, ensuring a correct thread engagement and a reliable seal every time. This cap is confirmed to fit AP6 and AP8 models, making part verification straightforward for service technicians and equipment operators alike. Keep a spare on hand to avoid unnecessary interruptions during pump maintenance or storage.

Key Features

• OEM-Grade Steel Construction — Manufactured from black steel with NPT threading held to OEM dimensional tolerances, delivering the thread integrity and corrosion resistance expected from a genuine Multiquip part.
• Correct 1-1/2" NPT Thread Spec — Matches the port thread standard on AP6 and AP8 pumps exactly, threading in cleanly without reworking or chasing threads.
• Confirmed Fitment for AP6 and AP8 — Verified genuine OEM replacement for Multiquip AP6 and AP8 water pump models, eliminating guesswork when ordering.
• Maintains Port Integrity During Storage or Service — A properly fitted steel cap protects open pump ports from contamination, debris ingress, and accidental damage between jobs or during transport.
• Genuine OEM Part Number APRD27836 — Sourced directly through authorized Multiquip distribution channels, so the part number matches your service manual and parts diagram without cross-referencing required.

A threaded pipe cap seals an open NPT port on a pump housing, preventing contaminants such as dirt, debris, and moisture from entering the fluid path during storage, transport, or service intervals. On water pumps like the AP6 and AP8, maintaining clean, undamaged port threads is essential to achieving a leak-free connection when fittings or hoses are reinstalled. A missing or damaged cap can allow debris to compromise the pump's internal components or cause thread damage that makes future connections difficult to seal properly.
