13.5 mm Water Line End Cap

Product Overview

The SL-67 end cap is a short white plastic stopper that seals the dead end of a 13.5 mm poultry drinking pipe. It measures about 2 cm across and 1.8 cm tall, and each piece weighs only 1.4 g. The cap slides over or into the pipe end, closing the loop so the line holds pressure and water can be flushed cleanly through the circuit without spilling at the far end.

Every drinking line run needs a sealed end: without it, water spills out and the line cannot build the pressure the nipple drinkers expect. This small cap closes the final outlet, whether the run ends at a wall, at a row break, or at the farthest nipple on the line. Its simple shape means it is quick to remove for flushing or maintenance between flocks, and the bright white body makes it easy to spot during the final walk-through.

Key Features and Benefits

• Seals the line end - closes the dead end of the 13.5 mm pipe so pressure holds for the nipples.
• Tiny 1.4 g weight - no load at all on the suspended pipe end or its support.
• Short 1.8 cm profile - fits tight corners where the run finishes near a wall or post.
• Simple push-on shape - installs by hand with no tools or extra parts.
• White molded body - easy to spot when inspecting the line ends at both sides of the house.
• Easy to remove - pulls off for flushing and draining between flocks.

Materials and Quality

The cap is molded from rigid white plastic that keeps its rim round even after repeated removal and refitting. The skirt forms a snug push-on fit over the pipe end, and the closed top keeps the circuit sealed without loose gaskets or O-rings. Smooth surfaces mean no crevices where algae could collect between flocks. Each batch is checked for rim roundness and consistent wall thickness, and pieces with flash or cracks are removed before packing so the seal stays reliable.

The 2 cm diameter and 1.8 cm height match the standard 13.5 mm pipe end with a snug skirt, so the cap does not ride loose when the line is bumped during cleaning. At only 1.4 g, the cap adds nothing to the suspended weight of the row, which means the last nipple on each line stays at the correct drinking height.

How to Use and Maintain

Push the cap firmly onto the cut pipe end until it seats against the stop. When the system is drained between flocks, pop the cap off to let the line empty completely, then flush clean water through until it runs clear. Check the rim for deformation at each flock change; if the cap no longer holds a seal, replace it rather than wrapping it in tape. Store caps loose in a dry box with other small fittings so they are ready when a row end needs closing.

Because the cap is removed so often for flushing, it is the easiest fitting to lose; staff often keep a small string tie between the cap and the pipe end so it cannot fall into the litter. During the empty-house washdown, leave the caps off overnight so the pipe interior dries out before new litter goes in. If a cap sits loose after many seasons, the simple fix is replacement rather than tape, and spare caps cost little enough to order by the box.

Applications

This end cap is used on every closed run of 13.5 mm nipple drinking line in broiler, layer and breeder houses: at the wall end, at the end of a shorter branch, and wherever a tee-fed row stops before reaching the opposite wall. It also suits temporary or movable lines that crews re-route between flocks.

It is also the natural spare part for line maintenance, since caps get lost or broken during flushing. Distributors pack end caps with couplings, elbows and tees so customers receive a complete kit for building or repairing 13.5 mm drinking loops, and farms keep a handful in the toolbox for quick end replacements. Because caps are cheap and small, buyers often order them together with couplings and end fittings rather than as a separate shipment. The caps are supplied in bulk cartons for farm and distributor use.

Frequently Asked Questions

Q1: Which pipe size does this cap fit?

The cap is made for the standard 13.5 mm poultry drinking pipe used in nipple drinker systems.

Q2: How do I remove it for flushing?

The cap pulls off by hand; lever gently with a flat tool if it is stuck after long use on the line.

Q3: Can I reuse the same cap many times?

Yes, the plastic rim is designed for repeated removal and refitting; replace it only if the fit becomes loose.

Q4: Should I add tape around the rim?

Tape is not needed when the cap seats properly; if it leaks, check the pipe end is cut square and undamaged.
