Reliance (specifically through its SharkBite brand) external couplers are innovative push-to-connect fittings designed for quickly and securely joining various types of piping without the need for soldering, glue, or specialized tools. They are widely used in plumbing applications for both new installations and repairs.

Product Details

Functionality: An external coupler provides a quick, watertight, and reliable connection between two sections of pipe. It works by having an internal gripping mechanism (often a stainless steel grab ring with teeth) that firmly bites onto the pipe's outer surface, while an O-ring creates a watertight seal. The "external" designation means the coupler fits over the outside of the pipes being joined.
Design: These couplers typically feature a compact, robust body made of lead-free DZR brass. They have push-fit ends on both sides, allowing for easy insertion of the pipe.
Compatibility: A key advantage is their versatility. They are designed to connect different pipe materials, including copper, PEX (cross-linked polyethylene), CPVC (chlorinated polyvinyl chloride), PE-RT, or SRD9 HDPE pipes, often in any combination.

Product Parameters

Material: Lead-Free DZR Brass body, EPDM O-ring, Stainless Steel Grab Ring, Polysulfone Tube Support Liner (for PEX).
Sizes: Available in various nominal pipe sizes, e.g., 1/2", 3/4", 1", etc.
Pressure Rating: Typically rated for a maximum working pressure of 200 PSI (pounds per square inch).
Temperature Rating: Generally rated for a maximum temperature of 200°F (93°C).
Service: Primarily designed for potable water and hydronic heating applications.
Certifications: Often design certified and agency listed to standards such as NSF/ANSI 61, NSF/ANSI 14, and ASSE 1061 for use in potable water and hydronic heating water distribution. Approved for use underground and behind walls without access panels.

Product Advantages

Ease of Installation (Push-Fit): This is the primary advantage. No soldering, crimping, glue, or special tools are required, significantly reducing installation time and complexity. This makes them ideal for DIY projects and rapid repairs.
Versatility: Ability to connect different pipe materials (copper, PEX, CPVC) in any combination offers great flexibility in plumbing systems.
Reliability & Durability: Constructed from high-quality, corrosion-resistant materials like DZR lead-free brass and EPDM O-rings, ensuring a long-lasting, leak-free connection.
No Fire Hazard: Eliminates the need for torches and open flames, making installation safer, especially in existing structures.
Accessibility: Approved for underground and behind-the-wall installations without the need for access panels, simplifying future maintenance.
Reduced Labor Costs: Faster installation translates directly into lower labor costs for professionals.
Instant Connection: Provides an immediate, secure connection once the pipe is fully inserted, indicated by a "click" or tactile feedback.

Important Considerations

Proper Pipe Preparation: Ensure pipes are clean, cut squarely, and deburred to prevent damage to the O-ring and ensure a proper seal.
Insertion Depth: It's crucial to ensure the pipe is fully inserted into the coupler until it reaches the pipe stop. Marking the insertion depth on the pipe before connecting can be helpful.
Compatibility: While versatile, always double-check the specific coupler's compatibility with the pipe materials you intend to join.
No Reuse (Generally): While some specific SharkBite fittings can be demounted with a special tool, repeated reuse is generally not recommended as it can compromise the seal.
System Pressure/Temperature: Ensure the operating pressure and temperature of your system do not exceed the coupler's maximum ratings.
Storage: Store couplers in a clean, dry environment to protect the internal components.
