Coupling 5/16" PTC x 1/4" PTC Push-to-Connect Polypropylene, SharkBite 25422 The SharkBite 25422 push-to-connect coupling enables fast, tool-free joining of 5/16" and 1/4" tubing in fluid transfer, pneumatic, and appliance applications. Molded from lead-free polypropylene, it features integrated stainless steel grip rings and EPDM O-rings at both ends to create secure, leak-free connections with PEX, polyethylene, nylon, or soft copper tubing?without soldering, clamps, or adhesives. Its compact design allows installation in tight spaces, while the push-to-connect mechanism supports easy disassembly and reuse: simply depress the release collar and withdraw the tube. ANSI-certified for performance and safety, this coupling is ideal for ice makers, reverse osmosis systems, humidifiers, and low-pressure air lines. Features - Dual-size push-to-connect coupling: 5/16" PTC x 1/4" PTC for mixed-tubing transitions - No tools, solder, glue, or clamps required?install or disconnect in seconds - Stainless steel grip teeth and EPDM O-rings ensure reliable sealing and pull-out resistance - Compatible with PEX, PE-RT, polyethylene, nylon, and soft copper (? 70 psi, 180F max) - Lead-free polypropylene body resists scaling, corrosion, and chemical degradation - Reusable design allows system modifications without cutting or replacement - Smooth internal flow path minimizes pressure drop and turbulence - Meets ANSI/NSF 61 and 372 standards for potable water safety - Compact size fits easily behind appliances and in utility closets - Visual insertion depth indicators ensure proper tube seating Specifications - Brand Name: SharkBite - Model Name: SharkBite 25422 - Part Number: 25422 - Product Type: Coupling - Connection Type: Push-to-Connect (PTC) - End 1 Diameter: 5/16 in - End 1 Type: PTC - End 2 Diameter: 1/4 in - End 2 Type: PTC - Material: Polypropylene - Seal Material: EPDM O-Ring - Grip Mechanism: Stainless Steel Teeth - Max Pressure: 70 psi - Max Temperature: 180F - Product Dimensions: 1.25 x 0.62 x 0.62 in - Item Weight: 0.100 lb - Certifications: ANSI Certified, NSF/ANSI 61 372, Lead-Free - Packaging Type: Bagged - Hazardous Material: No - Country of Origin: United States - UPC: 697285254220 - Global Trade Identification Number: 00697285254220 - Manufacturer: Reliance Worldwide Corporation Product Application This coupling is used by plumbers, appliance technicians, and DIYers to connect dissimilar tubing sizes in point-of-use water systems?such as linking 5/16" supply lines from shut-off valves to 1/4" inlet ports on refrigerators, RO units, or whole-house humidifiers. Its push-to-connect reliability eliminates soldering risks near combustible materials and supports rapid service calls where time and space are limited. Common in retrofits, new construction, and mobile home installations, the 25422 ensures leak-free performance in low-pressure, non-continuous-flow applications while allowing future upgrades without system drain-down or torch work. Trusted for code compliance and ease of use, it delivers professional results with minimal skill or tool investment.
