Introducing the 1.375 x 24 HUB Solvent Trap

A solvent trap with a 1.375 x 24 HUB thread is a specialized maintenance accessory designed for firearm cleaning. It threads onto the muzzle of compatible firearms and captures solvent, fouling, and debris that would otherwise drip from the barrel during bore cleaning. By containing liquids and residues, a solvent trap helps maintain cleaner workspaces, reduces waste, and facilitates more efficient maintenance.

What is a HUB thread?
HUB (HEMTT Universal Barrel) denotes a common thread size and pitch used on certain firearm barrels and muzzle devices. The designation 1.375 x 24 specifies a nominal major diameter of 1.375 inches with 24 threads per inch. This standardization ensures compatibility between barrels, muzzle devices, and aftermarket accessories manufactured to the same specification.

How a solvent trap with 1.375 x 24 HUB thread is used

• Verify compatibility: Confirm the firearm’s muzzle thread matches 1.375 x 24 HUB. Using incorrect threads can damage components or create unsafe conditions.
• Mounting: Ensure the firearm is unloaded and pointed in a safe direction. Thread the solvent trap onto the muzzle by hand until securely seated; use appropriate tools only if specified by the manufacturer.
• Cleaning operation: Apply bore solvent and run brushes and patches as recommended. The solvent trap collects expelled solvent and fouling for later disposal.
• Maintenance and disposal: After cleaning, remove the solvent trap, empty collected fluids into an approved container, and clean the trap per manufacturer guidance. Inspect threads and sealing surfaces for wear before reuse.

Safety and legal considerations
Use solvent traps only for their intended purpose—firearm maintenance. Some jurisdictions regulate accessories that resemble or can be converted into other muzzle devices; consult local laws and manufacturer documentation. Always follow safe firearm handling practices: treat every firearm as loaded, keep the muzzle pointed in a safe direction, and verify the chamber is clear before maintenance.
