Qwik Tee's and Ell's allow up to 90 deg connections of all common household drain, waste and vent pipes quickly and easily without using special tools or fittings. Because they're exceptionally flexible and long, they're the ideal replacement for fittings at the joint during alteration or repair. Fits cast iron, copper, steel or lead pipe. Not recommended for underground connections. Do not use in pressure applications. Adapts to other pipe sizes with Qwik Bushings.
