PVC 90° Winkel Rohrverbinder Verbindern Fittings 1 2" 3 4" 1" ~ 2" Innengewinde

Match the fitting size to your pipe's nominal diameter: 1/2" for DN15 pipe, 3/4" for DN20, 1" for DN25, 1-1/4" for DN32, 1-1/2" for DN40, and 2" for DN50. If you are unsure, measure the outer diameter of your pipe and compare it to standard nominal pipe size (NPS) charts — nominal size is not the same as the actual outer diameter.

These fittings use NPT-compatible female threads, which are mechanically compatible with both PVC and CPVC male-threaded pipe or nipples of the same nominal size. However, CPVC is typically used for hot-water lines, and these PVC fittings are not rated for hot water or steam service. For cold-water and irrigation applications, compatibility is straightforward.

Yes. Apply two to three wraps of PTFE (plumber's) tape to the male threads before assembly, or use a pipe thread sealant compound rated for PVC. This ensures a leak-free seal and makes future disassembly easier. Do not overtighten — PVC threads can crack under excessive torque. Hand-tight plus one to two turns with a strap wrench is typically sufficient.

PVC is well-suited for outdoor and underground irrigation applications. It resists moisture and soil chemicals effectively. For above-ground outdoor use, prolonged direct UV exposure can cause gradual surface degradation over several years; painting with a latex-based paint or wrapping exposed sections provides adequate protection for most installations.

Pressure ratings for PVC fittings vary by size and wall schedule. As a general reference, Schedule 40 PVC fittings in the 1/2"–2" range are typically rated between 150–480 PSI at room temperature, with ratings decreasing as temperature rises. Contact us to confirm the specific pressure rating for your size and application before use in pressurized systems.

If you are completing a single repair or a small project with a known fitting count, ordering individual pieces avoids leftover stock. For larger irrigation layouts, new plumbing runs, or projects where you expect to need spares, multi-packs of 3, 5, or 10 offer a lower per-unit cost. Select your size and quantity combination from the variant options above before adding to cart.

PVC fittings can be used in low-pressure compressed-air distribution in workshop settings, but this application carries additional risk compared to water service. PVC can become brittle over time with certain compressor oils and UV exposure, and a failure under air pressure can be more hazardous than a water leak. Always verify that your operating pressure is well within the fitting's rated limit and inspect fittings regularly.
