In-Line Grease Hose Swivel – 1/8" NPT Standard

Overview

The LockNLube In-Line Grease Hose Swivel (LNL231) is designed for use as a grease gun hose accessory, providing 360-degree in-line rotation to reduce hose stress and improve maneuverability across manual, cordless, and pneumatic grease gun applications.

Technical Features

• 1/8" NPT standard thread: Matches the thread specification of virtually every manual grease gun and is engineered to align with the threads and specs of cordless grease guns from most major manufacturers, ensuring broad compatibility without adapters.
• 10,000 PSI pressure rating: Supports the full output range of hand pump, cordless, and pneumatic grease guns, eliminating the swivel as a pressure bottleneck in the lubrication line.
• Reinforced structural design: Built to resist lateral pressures applied to the grease gun hose — not only the internal pressure of grease flow — reducing the risk of hose fatigue, kinking, or fitting failure at the connection point.
• In-line swivel configuration: Allows the hose to rotate freely along its axis during operation, relieving torsional stress on the hose and extending hose service life.
• Best-selling LockNLube platform: Identified as the brand's traditional and most widely adopted swivel model, indicating proven field performance across a broad range of grease gun setups.

Applications

• Replacement or upgrade swivel fitting for manual hand-pump grease guns requiring 1/8" NPT connections.
• Compatible upgrade for cordless grease guns from most major manufacturers where factory hose swivels are absent or undersized for job-site demands.
• Suitable for pneumatic grease gun setups operating at high discharge pressures up to 10,000 PSI.
• General preventive maintenance operations where repeated hose repositioning creates lateral load on the hose assembly.
