The chain is fine...but I ordered the wrong size. Nine links of the chain I ordered equals six of the size I wanted. My error...
How can I straighten out the springs? I can't use them coil uo as is.

When your plumbing run demands a clean directional change between two different pipe diameters, a poorly matched fitting can mean leaks, pressure loss, or hours of rework. These PVC 90° reducing elbows are designed for DIY homeowners, plumbers, and irrigation installers who need a dependable, pressure-rated solution for reducing pipe transitions at a right angle — without compromise.
Each PVC 90° reducing elbow features solvent-weld (Klebemuffe) sockets on both ends, manufactured from rigid PVC to PN16 pressure rating. The larger socket (Großer ID) and smaller socket (Kleiner ID) span a range from 25×20mm (~1"×¾") up to 110×90mm (~4"×3½"), covering the most common residential and light commercial pipe size combinations. Wall thickness is proportional to pipe diameter and PN16 specification.
Typical use cases include domestic cold-water supply line reductions, garden and drip irrigation manifold transitions, rainwater harvesting downpipe connections, and pool or spa plumbing where a 90° direction change with a size step-down is required in a single fitting.
Covers 25×20mm through 110×90mm — 23 size combinations to match your exact pipe reduction needs.
Rated to 16 bar at 20°C, suitable for cold-water supply, irrigation, and drainage applications.
Klebemuffe (solvent-weld) design creates a permanent, leak-free bond with standard PVC solvent cement.
Available in White, Blue, and Grey to match your existing pipework or system color-coding conventions.
Rigid PVC construction resists rust, scale, and most common household chemicals for long service life.
Order 1, 2, 5, or 10 pieces per size — ideal for single repairs or multi-point installations.

The size format is "Larger OD × Smaller OD" (e.g., 40×25mm means the larger socket fits 40mm OD pipe and the smaller socket fits 25mm OD pipe). Measure the outer diameter of both pipes you need to connect, then select the matching size combination from the variant options above.
These fittings use solvent-weld (Klebemuffe) sockets, which require standard PVC solvent cement (also called PVC glue or solvent weld adhesive). Apply primer first if recommended by your cement manufacturer, then apply cement to both the pipe end and the socket interior before pushing together with a quarter-turn. Allow adequate cure time before pressurizing.
These PVC PN16 elbows are rated for cold-water service up to approximately 60°C. For continuous hot water above 60°C, CPVC or other heat-rated materials are recommended. Always verify the temperature requirements of your specific application before installation.
PVC is resistant to corrosion and most soil chemicals, making it suitable for buried installations. For above-ground outdoor use, prolonged UV exposure can cause gradual degradation — consider wrapping or painting exposed sections, or use UV-stabilized fittings if long-term outdoor exposure is expected.
These fittings are rated PN16 (16 bar) at 20°C. As water temperature increases, the safe working pressure decreases — at 40°C the de-rating factor is approximately 0.74, and at 60°C approximately 0.40. Always apply the appropriate de-rating factor for your operating temperature when designing a pressurized system.
No — these are solvent-weld (glue) socket fittings only. They are not compatible with push-fit, compression, or threaded connection systems. Ensure your existing pipework uses the same connection method, or use an appropriate transition fitting to switch between systems.
White, Blue, and Grey variants are identical in material, pressure rating, and dimensions. Color is used for system identification — for example, blue is commonly used for cold-water supply lines in some plumbing conventions, while grey is often associated with drainage or waste systems. Choose the color that matches your existing pipework or local coding practice.
