13.5 mm Water Line Elbow

Product Overview

The SL-69 elbow is a translucent white 90 degree fitting for the standard 13.5 mm poultry drinking pipe. Each leg of the bend measures 4.5 cm, and the whole piece weighs about 7.2 g. Both ends open as smooth sockets, so the rigid drinking pipe slides in from two directions and the line turns a right angle neatly without kinking the tube or creating a dead pocket for sediment.

Elbows are used wherever a suspended drinking line must change direction: along a side wall, around an end door, or between the main loop and a cross-over section. The translucent body makes it easy to see whether the bend is fully filled with water or holding an air pocket during the initial pressure test. The uniform legs also mean the corner can be placed precisely on the planned layout without offsetting the next nipple row.

Key Features and Benefits

• 90 degree socket bend - turns the 13.5 mm pipe cleanly at corners and wall runs.
• Identical 4.5 cm legs - both sides seat the pipe the same way, simplifying layout planning.
• Translucent body - trapped air and blockages show up through the wall during checks.
• Sturdy 7.2 g build - resists flexing when the line is lifted or lowered each day.
• Smooth socket bores - pipe inserts evenly without scraping or jamming on mold marks.
• One-piece molding - no glued joint at the bend where cracks tend to form over time.

Materials and Quality

The elbow is injection molded from translucent plastic with a reinforced bend radius that keeps the internal water passage smooth. The two socket openings stay round and evenly sized, so the pipe bottoms out at the same depth on both sides. The material resists the humid, dusty air of poultry houses and does not rely on surface coatings. Finished elbows are checked for bent sockets, short shots and visible cracks before they are packed into export cartons, keeping the part consistent order after order.

The 4.5 cm legs are long enough that each pipe end reaches the socket stop without covering the bend itself, leaving the curved center visible for inspection. The reinforced radius keeps the internal bore open at the turn, so the elbow does not introduce a narrow spot that would slow the whole row.

How to Use and Maintain

Slide the cut pipe ends into the two sockets until they seat, keeping the bend oriented so the water path follows the planned route. Add clamps if the house uses higher line pressure. When flushing the system, run water through the elbow and check that no air pocket lingers at the top of the bend. During line height adjustment, lift the line at the supports rather than pulling on the elbow itself, and replace any fitting that shows hairline cracks after a cold winter or rough handling.

Corner elbows take the most pulling force when the line is raised, so check each bend while the winch operates: a groaning or twisting elbow usually means the pipe has half-left its socket. During the first fill of a refurbished house, tilt the bend upward while flushing so trapped air escapes before the line settles. If a crack appears at the bend radius, replace the whole elbow instead of patching it, since a split at a corner will only grow under pressure. Keep spare elbows near the house entrance for same-day swaps.

Applications

This elbow is used on automatic nipple drinking lines wherever the 13.5 mm loop must turn a corner: along side walls, around doorways, and where the main loop crosses from one house section to another. It suits broiler, layer and breeder installations alike, and is the natural choice for rectangular houses where the loop must follow the building outline.

It is also a practical spare part for maintenance teams, since corner elbows take the most mechanical stress on a suspended line. Distributors bundle elbows with tees, couplings and end caps as a complete repair set for the 13.5 mm socket fitting range, which lets farms order everything needed for one house in a single shipment. Corner elbows are checked first on any suspended-line inspection, because they carry the pull of the winch every day of the flock. These elbows are packed in bulk cartons ready for distributor shelf stock.

Frequently Asked Questions

Q1: Which pipe size does this elbow fit?

The sockets are made for the standard 13.5 mm poultry drinking pipe used in nipple drinker lines.

Q2: Can it be rotated after installation?

The fitting can be oriented during assembly; once the pipe is seated, treat it as a fixed corner of the line.

Q3: Why does my elbow hold air?

Air pockets can collect at the top of a bend; flush the line until clear water runs and check the translucent body for bubbles.

Q4: Do I need clamps on both ends?

The socket fit is reliable at normal drinking line pressure; clamps are recommended on high-pressure or aging lines.
