Details

This dahl Quick Grip Straight Supply Stop is a premium 1/4-turn mini ball valve designed for fast, reliable shut-off on 1/2 inch copper, PEX, or CPVC water lines. Made in Canada from 100% North American, lead-free brass, this push-fit stop valve is ideal for contractors and DIY homeowners looking for a clean, professional-grade installation without special tools.

The dahl QUICK-GRIP straight supply stop is engineered for plumbers who need fast, reliable fixture connections without soldering. At The Contractors Site, we supply this 1/2 x 3/8 OD comp straight configuration to Ontario plumbing contractors and tradespeople running production fixture work in residential and light commercial builds.

The Quick Grip design works similarly to popular SharkBite-style push-fit fittings, allowing you to simply push the valve onto the pipe for a secure, watertight connection. There is no soldering, crimping, or gluing required, which makes this an excellent choice for quick repairs, remodels, and tight spaces where open flame or extra tools are not practical.

QUICK-GRIP Means No Torch, No Flux, No Delay

Push the copper pipe into the dahl QUICK-GRIP inlet and the mechanical locking ring grips the pipe instantly — forming a watertight, pressure-rated connection without any heat, flux, or solder. For plumbers working on fast-paced jobs where efficiency per fixture is critical, eliminating soldering on every supply stop connection adds up to real time savings by end of day.

Key features and benefits:

  • 1/4-turn mini ball valve for smooth, easy on/off control of water supply

  • Push-fit connection for 1/2 inch copper, PEX, or CPVC pipe

  • Similar installation style to SharkBite push-fit fittings for fast, tool-free connections

  • Ideal for hooking up toilets, bidets, sinks, and faucets

  • Designed for use where the water supply pipe comes from the floor

  • Manufactured in Canada from premium US lead-free brass

  • Every valve is factory-tested for quality and leak-free performance

  • Backed by dahl's lifetime transferable warranty

Use this dahl QUICK-GRIP supply stop to upgrade shut-off valves during bathroom and kitchen renovations, new construction, or emergency repairs. It delivers the convenience of a SharkBite-style push-fit with the long-term reliability and warranty support that professional plumbers and contractors trust.

dahl Quality You Can Rely on for Long-Term Service

Every supply stop is a service shutoff point. When a faucet fails or a supply line needs to be replaced five years from installation, the valve needs to seat cleanly and open fully without seizing. dahl builds their supply stops to last through the service life of the building — not just the warranty period.
