Ruisongbuild ASTM PVC Couplings: Precision Fittings for Imperial Systems
When working on projects based on North American piping standards, accuracy is everything. Ruisongbuild’s ASTM Standard PVC Couplings (also known as straight sockets or pipe joiners) are engineered to fit perfectly with Schedule 40 and Schedule 80 PVC pipes. Measured in true inches based on the Iron Pipe Size (IPS) system, our fittings provide a reliable, permanent solvent weld bond for residential, commercial, and industrial plumbing infrastructures.

Frequently Asked Questions
Q1: What is the difference between an ASTM coupling and a DIN coupling?
A: The main difference is the measurement system. ASTM couplings use the imperial system measured in inches (e.g., 1/2″, 1″, 2″) and match Schedule 40 or 80 pipes. DIN couplings use the metric system measured in millimeters (e.g., 20mm, 32mm, 50mm). They are not interchangeable.
Q2: What is a “Slip x Slip” coupling?
A: A “Slip x Slip” coupling has smooth sockets on both ends. It is designed to slide onto the outside of a pipe and be permanently joined using PVC primer and solvent cement (glue). It does not have threads.
Q3: What is the difference between Schedule 40 and Schedule 80 PVC couplings?
A: Schedule 80 couplings have thicker walls and are rated for higher pressures compared to Schedule 40. Schedule 40 couplings are typically white and used for residential/pool applications, while Schedule 80 fittings are typically gray and used for heavy industrial applications.
Q4: How do I know what size coupling to buy?
A: In the ASTM system, PVC pipes and fittings are measured by their Nominal Pipe Size (NPS), not the actual physical outside diameter. For example, a 1-inch pipe requires a 1-inch coupling, even though the actual outside diameter is slightly larger.
Q5: Are Ruisongbuild ASTM couplings safe for drinking water?
A: Yes. Our white Schedule 40 PVC couplings are manufactured from lead-free, non-toxic materials and are perfectly safe for potable drinking water systems and aquaculture.
