13.5 mm Water Line Elbow

Product Overview

The SL-37 13.5 mm elbow is a red plastic barb fitting designed to change the direction of a poultry nipple drinking line by 90 degrees. It is used wherever a water line must turn a corner, rise along a wall, or route around an obstacle inside a poultry house. The fitting has two barbed sockets, each 3.9 cm long, so the flexible 13.5 mm drinking hose can be pushed on from both sides and secured with small hose clamps for a firm, leak-resistant joint. Farmers reach for this part whenever the suspended loop cannot run in a straight line to the next nipple row.

Because the elbow is produced as a single molded piece, it has no glued seams or loose parts that could come apart under line pressure. Its compact size keeps the water route neat, and the bright red color makes the fitting easy to locate during routine inspection. This model is a standard replacement part for automatic nipple drinker systems in broiler, layer and breeder houses. It is small enough to fit in a maintenance pocket, which is why crews carry spares on every walk-through of the house.

Key Features and Benefits

• 90 degree direction change - turns the drinking line around corners and obstacles without forcing the hose into sharp kinks that restrict flow.
• Barbed sockets on both ends - the stepped barb profile grips the inner wall of the 13.5 mm hose once pushed fully home, resisting pull-out during line moves.
• Lightweight at 4 g - adds almost no load to the suspended water line, so existing support spacing remains correct.
• Uniform 3.9 cm legs - both sides are identical in length, making installation symmetrical and easy to plan from a ladder.
• One-piece molded body - no assembled components to loosen, crack or weep at glued joints after long service.
• Easy to identify - the red body stands out against white pipe and blue tubing during daily inspection walks.

Materials and Quality

The elbow is injection molded from durable plastic that resists the moisture-rich, ammonia-containing air inside poultry houses. The surface is smooth and free of molding flash, and the barb ridges are formed in the same molding step so they cannot separate from the body. Each piece is visually checked for cracks, incomplete filling and deformed barbs before packing. Red pigment is mixed into the material rather than painted on, so the color stays consistent even after long contact with drinking water and disinfectant residues. The material also tolerates the small temperature swings between summer and winter inside a closed house.

How to Use and Maintain

Push the 13.5 mm hose firmly over each barbed end until it reaches the stop ridge, then add a small hose clamp at each joint if the line runs at higher pressure. When the house is emptied for cleaning, flush the line with clean water and inspect the elbow for algae buildup or hairline cracks. Replace any fitting that shows visible cracking or weeping at the joint. Keep spare elbows in a dry store together with other line fittings so maintenance can be completed without delaying the next flock, and avoid stepping on dropped pieces in the litter to keep the barbs straight.

During the flock, check the corner elbows once a week: a slight weeping at the barb usually means the hose has loosened after the line was raised. Keep spare pieces in the truck so a cracked corner can be swapped on the same visit, without waiting for a new carton delivery. Well-placed corners also keep the nipple rows at an even height, which helps every bird drink at the same level.

Applications

This elbow is used in automatic nipple drinking systems for broilers, layers, breeders and parent stock. It is the standard choice for turning the water line along side walls, around door openings and between house sections where the straight run of hose must change direction. It also suits slatted areas and curtain-sided houses where the loop must follow the building shape.

It also suits small-scale farms, research stations and poultry equipment distributors who need low-cost replacement fittings. Distributors commonly stock this part alongside tees, couplings and end caps to offer a complete repair kit for 13.5 mm drinking lines. Export buyers often order it in bulk because it is a fast-moving spare part on every farm they supply.
