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 a leaking joint or a failed pipe connection brings your project to a halt, you need a fitting you can trust to hold. Whether you are a homeowner tackling a garden irrigation upgrade, a contractor running cold-water supply lines, or a DIYer extending a drainage run, these PVC solvent weld socket couplings give you a clean, permanent, pressure-rated joint every time.
Each coupling is manufactured from rigid white PVC (polyvinyl chloride) and rated to PN 10 bar (145 psi) for cold-water service. The socket (Muffe) design accepts standard metric PVC pipe on both ends via solvent cement bonding. Available inner diameters span 20 mm (approx. ¾ in) through 110 mm (approx. 4⅓ in), covering the most common residential and light-commercial pipe sizes.
Typical applications include cold-water supply plumbing for PVC solvent weld pipe systems, garden and agricultural drip irrigation manifolds, rainwater harvesting and downpipe extensions, and pool or spa circulation pipework where a straight inline coupling is required.

Measure the outer diameter (OD) of your existing PVC pipe, then match it to the corresponding nominal size. For example, a pipe with a 25 mm OD typically uses a 20 mm nominal fitting. If you are unsure, check the markings printed on your pipe — the nominal diameter is usually stamped directly on the pipe wall. When in doubt, select the next size up and verify fit before cementing.
These fittings are rated to PN 10 bar (approximately 145 psi) at 20 °C (68 °F). Working pressure decreases as water temperature rises, so these couplings are intended for cold-water service only. Do not use them in hot-water supply, steam, or compressed-air applications.
Yes. PVC is inherently non-corrosive and will not rust, scale, or degrade when exposed to chlorinated tap water, mild fertiliser solutions, or common pool chemicals. It is also resistant to most dilute acids and alkalis encountered in residential plumbing and irrigation. For aggressive chemical environments, verify chemical compatibility before installation.
These socket couplings are designed for standard metric PVC pressure pipe conforming to DIN 8061 and ISO 1452. They are not designed for imperial (inch-nominal) pipe or CPVC pipe. Always confirm that your pipe's outer diameter matches the fitting's socket bore before applying solvent cement.
Yes, with appropriate precautions. PVC is suitable for direct burial in soil when installed at adequate depth to prevent mechanical damage. For above-ground outdoor use, prolonged UV exposure can cause surface chalking over time; painting with a water-based exterior paint or wrapping with pipe insulation will extend service life. These fittings are not rated for continuous direct sunlight exposure without UV protection.
Handling strength is typically achieved within 5–15 minutes at room temperature. Full cure for pressure testing generally requires 24 hours at 20 °C (68 °F). Cure time increases in cold conditions and decreases in warm conditions. Always follow the solvent cement manufacturer's instructions for set and cure times before pressurising the system.
Multi-piece packs offer a lower per-unit cost and ensure you have spares on hand for repairs or future extensions without placing a new order. For larger projects — such as irrigation manifolds, multi-branch drainage runs, or pool plumbing — ordering a pack of 5 or 10 pieces upfront saves time and reduces the risk of project delays caused by a missing fitting.
