Multifunctional Aluminum-Plastic Pipe Rounding Tool | Flaring 16/20/25/32mm pipes | Manual Pipe Expander and Flaring Tool | PVC Conduit Anti-Flattening Tool | Damage-Free, One-Step Forming

A professional tool for rounding, expanding, and flaring 16/20/25/32mm pipes. It ensures smooth flaring and tight connections, eliminating the risk of leaks.

Key Features:
All-in-One, Versatile Compatibility: Combines rounding, pipe expansion, and flaring functions into a single tool. Easily handles various sizes—including 16 mm, 18 mm, 20 mm, 25 mm, and 32 mm—of aluminum-plastic composite pipes, PEX pipes, PVC pipes, and PB pipes, meeting the diverse needs of both home renovation and commercial installation projects.

Precision-Engineered Materials, Sturdy and Durable: The entire tool is crafted from No. 45 steel, offering high strength, wear resistance, and durability. The core expanding head is precision-machined to balance hardness and toughness, resisting deformation even with long-term use and ensuring precise, reliable flaring every time.

Non-Slip Handle for Effortless Operation: The handle is ergonomically designed for a comfortable grip. Its non-slip surface ensures a secure hold even when wearing gloves or with sweaty palms, allowing for easy one-handed operation and significantly reducing fatigue during installation.

Smooth Expanded Edges for Tight Connections: The unique conical expanding head gently expands the pipe end into a standard circular shape. After flaring, the inner wall is smooth and burr-free, with a flat, rounded pipe opening. This ensures a tight, seamless connection, effectively preventing leaks and enhancing system safety.

Does not damage pipe walls, protects pipes: The tool applies even force during operation, gradually flaring the pipe opening. It will not scratch the inner aluminum foil layer of aluminum-plastic composite pipes or burst the walls of PVC pipes, thereby safeguarding the integrity and service life of pipe connections from the source.

Lightweight and portable, ready to use anytime: Weighing approximately 313 grams, the product’s lightweight design makes it easy to carry to any job site. Whether under a narrow sink or inside a cramped ceiling cavity, it can be used with ease.

Before & After Comparison:

Before Expansion: The pipe end is collapsed, deformed, and oval-shaped, making it difficult to insert into the fitting; forcing a connection can easily lead to leaks.

After Expansion: The pipe end is rounded, flat, and smooth, matching the fitting perfectly for a tight connection that eliminates leaks.

Applications:

Home Renovation: Installation of faucets, angle valves, water purifiers, and water heaters

Piping Projects: Connections for heating systems and underfloor heating manifolds

Professional Fields: Air conditioning and refrigeration, gas delivery piping systems
