The Multiquip 508880 Allen Plug 1/8 NPT is a genuine OEM replacement designed for the AR14H asphalt ride-on roller. Sourced directly from Multiquip, this plug is an exact match for the original component and installs without any modification to the existing port. Confirm part number 508880 against your machine's parts manual before ordering to ensure a correct fit for your AR14H.
Key Features
- Genuine OEM Material Grade — Manufactured to the same thread specification and material standard as the original, ensuring a leak-free seal at the 1/8 NPT port.
- Direct Port-Thread Match — Threaded to NPT standard for a secure, wrench-tight fit into existing 1/8 NPT ports — no re-tapping or thread chasing required.
- Verified AR14H Fitment — Confirmed OEM fitment for the Multiquip AR14H asphalt ride-on roller series.
- Leak Prevention — A properly seated Allen plug maintains system pressure and prevents fluid loss or contamination at capped ports, keeping hydraulic or fluid systems performing as intended.
- Hex-Socket Drive — Internal Allen hex recess allows precise torque application in tight spaces where a standard hex head would be difficult to access.
An Allen plug — sometimes called a socket pipe plug — is a threaded fastener used to seal an unused or service port in a fluid system. On equipment like the AR14H roller, these plugs cap hydraulic, oil, or coolant passages to prevent leaks and keep contaminants out of the system. A damaged, cross-threaded, or missing plug can result in fluid loss, pressure drop, or internal contamination that leads to premature component wear.
