P3 PT Coupling performed galvanized clamp P100300

PT Coupling's is a pre-formed, punch-type hose clamp from the PUNCH-LOK® line, engineered by PT Coupling for industrial hose assemblies. It’s manufactured from galvanized carbon steel, with a band width of ⅜″ and a nominal inside diameter rating of 13⁄16″. The clamp arrives “double-wrapped and formed to a given diameter,” meaning it is pre-shaped for a specific hose/fitting outer diameter and is ready for installation with compatible punch-clamping tools (such as the P-1000™, P-3000™ or P-38™ banding tool models) rather than requiring a traditional screw-type hose clamp tightening. With its galvanised finish, the clamp offers moderate corrosion protection for general indoor or light-outdoor industrial environments, while its carbon steel construction provides reliable mechanical strength for routine hose retention applications. It is manufactured in the U.S.A., and the ordering procedure requires measuring the outside diameter of the hose with its fitting and then selecting the next larger nominal clamp size.
Key Features
- PT Coupling P100300 (also called P3) clamp.
- It’s a pre-formed Punch-Lok hose clamp, ready to go out of the box.
- Made from galvanized carbon steel, so it handles general environments pretty well.
- 3/8" band width — pretty standard size for small hose clamping jobs.
- Sized at about 13/16" inside diameter once installed (picked based on your hose + fitting OD).
- Built double-wrapped, so it grips tight and stays consistent.
- Needs a Punch-Lok tool like the P-1000, P-3000, or P-38 to lock it in place (no screw tightening).
- Good for fuel lines, ag equipment, shop-built hose assemblies, and similar setups.
- Made in the USA, solid reliability overall.
