Steel Dust Cap for 1-1/2 Inch NPT Coupler

The Buyers Products QDDC241 steel dust cap protects a 1-1/2 inch NPT coupler from contamination. It is intended for hydraulic systems where debris could damage internal components during storage or transport.

Build quality and chain attachment

The steel construction resists impact and corrosion in workshop environments. An integrated chain secures the cap to the equipment so it remains available when the coupler is disconnected and prevents loss during maintenance.

Fits 1-1/2 inch NPT threads only

This cap threads onto a 1-1/2 inch NPT coupler and will not seal other thread sizes or standards. Buyers needing protection for different hydraulic port dimensions must select a matching cap.

Questions about this item

What coupler size does the 1-1/2 inch NPT thread fit?

The cap threads onto any 1-1/2 inch NPT quick coupler to seal the port when disconnected.

How much clearance does the attached chain need?

The steel chain adds only a few centimetres of length, so it fits in tight compartments without snagging.

How do I install the cap without cross-threading the NPT threads?

Start the cap by hand, turn clockwise until the taper seats firmly, then give a light wrench nip — do not force it.
