Premium UPVC Male-to-Female Insertion Socket Elbows & U-Type Trap Elbows

Streamline your routing configuration and create highly compact pipeline bends with our premium UPVC male-to-female insertion socket elbows and U-type water trap elbows, available at Atradesen.com. Molded from industrial-grade, non-plasticized polyvinyl chloride (UPVC), these water-delivery fittings provide exceptional structural strength, chemical resistance, and a solid 16kg pressure rating for water treatment loops, marine aquariums, and drainage manifolds.

Whether you are routing tight water lines inside a sump tank cabinet or installing an inline siphon trap to reduce noise, this specialized elbow series minimizes the physical footprint of your connections.

Innovative Male-to-Female Insertion (Socket) Elbow

Standard 90-degree elbows feature female sockets on both ends, meaning you must cut and glue separate short segments of straight pipe to link them directly to valves or other female ports. Our specialized Socket Elbow features a single-spigot design: one end is a standard female socket that solvent-welds directly onto standard pipes, while the other end is a male spigot (outer diameter). This male spigot slides directly into valves, union couplers, or other female pipe joints of the same nominal size, conserving space and reducing transitional adapters.

U-Type 180-Degree Elbow & Siphon Trap (Unassembled Parts)

Constructed by combining a male-to-female spigot elbow with a standard 90-degree female socket elbow, our U-Type Elbow is engineered to complete a tight, full 180-degree pipeline turn. This configuration is widely used as an inline water seal trap to prevent sewer odors from backing up, and to significantly reduce fluid noise by creating a continuous wet seal.

Note: The U-Type Elbow is shipped as **unassembled separate parts** by default. This allows you to manually adjust, rotate, and lock the branching elbows to your exact target angle during solvent welding.

⚠️ Sizing & Solvent Welding Guidelines

Nominal pipe dimensions are based on standard outer diameters. Please measure your pipe outer diameter before placing your order:

• Female Socket End (I.D.): The female socket end has an inner diameter designed to slip over standard pipes with outer diameters of: 20mm, 25mm, 32mm, 40mm, and 50mm.
• Male Spigot End (O.D.): The male spigot end has an outer diameter designed to insert directly into receiving female sockets of the same nominal size (20mm, 25mm, 32mm, 40mm, or 50mm).
• Solvent Welding Method: Both styles require standard UPVC/PVC solvent cement (glue) to create a permanent, high-strength chemical weld bond on all sliding joints.

Frequently Asked Questions (FAQ)

Q: What is a "male-to-female" or spigot elbow used for?

A: It is designed to plug directly into the receiving female end of a ball valve, union, or bulkhead fitting. By inserting the male spigot directly into the receiving body without cutting and gluing transitional pipe nipples, you can save valuable space and simplify the plumbing assembly.

Q: How does the U-Type Elbow act as a water trap and reduce noise?

A: When water flows through the 180-degree bend, a portion of the liquid remains trapped in the bottom of the curve, creating a natural wet seal. This seal blocks sewer gases from traveling back up the line and acts as a fluid cushion, significantly damping drainage and siphon noises in aquarium sumps.
