The KNIPEX Cobra 87 02 300 is a versatile 12-inch pump plier built to handle plumbing, maintenance, and assembly tasks with steady confidence. Its robust box joint design enhances joint strength and leverage, helping you maintain a secure grip across round, square, and hex-shaped workpieces. With a working capacity of up to 2-3/4 inches, this tool accommodates a wide range of fasteners and pipes, making it a dependable companion on many job sites.

Designed for quick, accurate sizing, the pliers feature fast push-button adjustment directly on the workpiece. This allows you to choose the correct opening without guesswork or repeated test adjustments, saving time and keeping your flow going. Once set, the tool self-locks on pipes and nuts and resists slipping, so you can work with less hand strain and greater control.

Key design features at a glance

• Adjustment at the touch of a button directly on the workpiece
• Self-locking on pipes and nuts: no slipping and lower hand effort, with comfort grip handles
• Gripping surfaces with hard teeth (about 61 HRC) for low wear and reliable grip
• Slim head and joint area for good access in tight spaces
• Secure hinge bolt catch prevents unintentional shifting

Why it fits into your workflow

The 87 02 300 blends form and function to support precise, repeatable results. The dual-component, comfort-grip handle is designed to reduce finger fatigue during longer tasks, while the pinch-free design helps protect your hands during frequent adjustments. The slim head and joint enable access in confined areas, so you can reach fasteners that other pliers struggle to reach. The hardened teeth deliver reliable grip on a variety of shapes, helping you maintain control even when working with slippery surfaces.

Typical daily use scenarios include fastener adjustments on plumbing lines, valve fittings, hose clamps, and small-diameter pipes. The combination of a strong box joint, self-locking action, and adjustable capacity makes this tool a practical choice for both professional tradespeople and serious DIYers who value consistent performance without sacrificing comfort.

Usage tips:

• Position the upper jaw against the workpiece and press the push button to set the opening.
• Then bring the lower jaw until the tool grips securely—no slipping and minimal hand force required.

Bottom line: the Cobra 87 02 300 is designed to deliver dependable, repeatable performance across a range of gripping tasks, with features that support comfort and efficiency on the job.
