(90 Pack YVSKM) PEX-A Expansion Rings with STOP 60 pcs 1/2 inch + 30 pcs 3/4 inch — F1960 Full-Flow Expansion Sleeves for PEX-A Pipe, Leak-Tight, Fast Install for Hot/Cold & Potable Water

• Built-In STOP for Depth-Controlled Insertion Prevents over-push and ensures every joint seats to the correct depth, reducing installation errors and improving long-term sealing performance. Ideal for large-scale plumbing where uniformity matters.
• ASTM F1960 Expansion-Fit | Full-Flow, No Reduction Expansion-fit design maintains the full internal diameter of the pipe—unlike crimp or clamp systems which may restrict flow. Supports higher water volume and smoother pressure delivery.
• Dual-Size Build for Real Installers: 60 pcs 1/2" + 30 pcs 3/4" One box handles most home distribution lines including mains and branch runs. Perfect for rough-in, remodels, repairs, radiant loops and hydronic manifolds.
• Hot/Cold + Potable Water Rated | Heating & Hydronic Safe Engineered for pressurized hot water systems, radiant floor heating, drinking water lines and circulating loops. Temperature-stable, chemical-resistant, built for long-term service life.
• Fast Tool-Driven Install | Expands → Inserts → Shrinks → Locks Works with F1960 expansion tool for rapid assembly. Once expanded, the ring contracts back and tightens over the fitting—the joint strengthens as it shrinks, delivering a leak-tight permanent seal.
