1/2 Inch White Water Line Coupling

Product Overview

This white straight coupling is the simple sleeve that joins two sections of 1/2 inch poultry water line pipe end to end. At 6 cm long and 5.5 g per piece, it is the longest straight joiner in the white fitting series and is used wherever a drinker line has to be extended or repaired along a row. The smooth, unmarked white body matches the other white fittings used on the main supply pipe.

Because the coupling is a plain sleeve, installers push one pipe end in from each side until both bottoms touch the center shoulder, making a continuous straight run. It is packed 200 pieces per bag and 6000 pieces per carton, which reflects how often this small part is consumed on full-house installations and retrofit projects across commercial poultry farms.

Key Features and Benefits

• Straight sleeve design - joins two 1/2 inch pipe sections in one straight line without elbows or offsets.
• 6 cm length - long enough to hold both pipe ends securely and keep the joint aligned along the row.
• Light 5.5 g body - adds almost no weight to suspended pipe runs, keeping winch effort low.
• Plain white finish - matches the rest of the white 1/2 inch fitting family for a consistent line look.
• High carton count - 6000 pieces per carton suits big projects and distributor bulk stock orders.
• Push-fit installation - no glue, no tools, just push the pipe ends in until they seat against the stop.

Materials and Quality

The coupling is injection molded in white plastic chosen for low moisture absorption and resistance to the humid air inside poultry houses. The inner bore is formed to a consistent diameter so that pipe ends slide in smoothly while still gripping firmly once seated. Wall thickness is even along the whole 6 cm length, which prevents the sleeve from bending out of shape under line tension.

Each bag is filled from the same mold, so replacements ordered years later still match the original pipe set. The plastic also tolerates the mild disinfectants used during house wash-down, keeping the coupling clean and functional between flocks.

The center stop inside the sleeve is molded to a fixed depth so both pipe ends meet at the same point, which keeps the line straight and avoids a hidden internal step that could trap sediment over time. The outer diameter of the sleeve matches the rest of the white series, so the coupling can be swapped with elbows and tees on the same line without adapters.

How to Use and Maintain

Cut the pipe ends square, push one end into the coupling until it reaches the center stop, then push the second end in from the other side. Support the joint with the nearby pipe holder clips so the coupling does not carry the whole line weight alone.

During routine flushing, run water through the joint and check for weepage; if a pipe slides out, reseat it and reposition the support clip. Store spare couplings in the dry farm tool cabinet to keep the plastic clean and flexible for the next repair.

When installing a whole new line, fit every coupling at eye level first and only then lift the pipe into the support clips, because a coupling that is not fully seated usually shows as a small drip that disappears once the line is relieved of its own weight.

Applications

This coupling is used on the main 1/2 inch supply pipe of poultry drinking systems, wherever the line is extended, repaired or reassembled between flocks. It appears in every new layer and broiler house that uses rigid 1/2 inch supply pipe along the ceiling.

It is also a favorite repair part because cracked supply pipe sections are usually replaced by cutting out the damaged length and joining the two cut ends with fresh couplings. Distributors carry it in high carton counts because it moves quickly on every farm servicing truck, and it can be combined with elbows and tees in one container for mixed orders.

Frequently Asked Questions

Q1: What pipe size does this coupling fit?

It is made for 1/2 inch water line pipe used in poultry drinking systems, matching the other white fittings in this series.

Q2: How is the joint sealed?

The push-fit sleeve grips the pipe by friction once both ends seat against the center stop; no glue or tape is required. A small hose clip at each end is optional and helps on lines that are lifted several times a day.

Q3: Can it be used underwater or buried?

This coupling is designed for suspended poultry house drinking lines; please contact us for submerged or buried piping requirements. If your house runs the line close to litter level, check that the support clips keep the joint clear of wet bedding.

Q4: How many pieces come in one carton?

Each bag holds 200 pieces and each carton holds 6000 pieces in total, suitable for bulk farm and distributor orders. Sample bags can be split for small farms that want to test the fit before a full project purchase.
