Material: Typically manufactured from High-Density Polyethylene (HDPE) or Polypropylene (PP). These materials are chosen for their high impact strength and resistance to chemicals.
Design: Features a characteristic "D" shape or D-shaped cross-section. The "short" designation refers to a compact body length compared to "long" variants.
Connections: Often utilizes a male threaded or nut-and-bolt mechanism to create a leak-proof seal.
UV Resistance: The black color is frequently achieved through UV stabilization, making these joints suitable for outdoor use where they are exposed to sunlight.
Sizes: Widely available in diameters ranging from 63mm to 315mm (roughly 2 to 12 inches).
Pressure Ratings: Commonly rated for standard pressures such as PN6, PN10, or PN16.
