Four Minute Big Head Spring Nipple

Product Overview

The SL-25 four minute big head spring nipple is a yellow clip-on poultry nipple drinker built for push-fit mounting onto vertical drinking pipes. A large two-wing clamp at the top grips the pipe, the red lower body holds the internal spring seal, and a short stainless steel pin hangs down for the birds to activate. The big-head version offers a wider clamp wing area for a firmer grip on standard pipe diameters.

The whole nipple stands 5.7 cm tall and weighs about 8 g, keeping both the pipe load and the piece cost low. When a chicken pecks or nudges the pin, the spring-loaded ball lifts and water flows; when the bird releases the pin, the spring returns it to the seat and flow stops. This on-demand principle keeps water fresh, reduces waste and limits wet litter across the house.

Key Features and Benefits

• Big-Head Two-Wing Clamp - the enlarged yellow wings press onto the pipe from both sides, giving a secure push-fit hold without tools or clamps.
• Spring-Loaded Internal Seal - the spring returns the ball to its seat after every drink, closing drips and protecting litter quality.
• Stainless Steel Actuation Pin - the metal trigger resists beak wear and corrosion, keeping flow consistent over long production cycles.
• Red Lower Body - the red base contrasts with the yellow clamp and the white pipe, making each nipple easy to locate during line inspection.
• Compact 5.7 cm Height - the short profile fits tight brooder setups and allows close nipple spacing on high-density lines.
• Light 8 g Per Piece - low weight simplifies shipping by the thousand and keeps the drinking pipe free of excess load.

Materials and Quality

The clamp wings are molded from flexible yellow engineering plastic that springs open and snaps closed around the pipe. The red base houses a stainless spring and ball, and the actuation pin is stainless steel for long service. Each nipple is tested for free pin movement and shut-off before packing, and batches are checked visually for color consistency and complete molding.

The yellow wings are made of a living-hinge plastic that returns to shape after thousands of snaps, and the red base protects the spring cartridge from dust. Material batches are sampled for wing stiffness before packing.

The enlarged yellow wings are tuned to snap firmly on standard pipe without over-stretching, and the living-hinge plastic is sampled for opening cycles before batch release. The red base protects the spring and ball from dust, while the stainless pin stays smooth against beak contact even when birds peck repeatedly. Because packing is by the bag, each bag is weighed at the pack house so installers know they received the full count. Material batches are also checked for drinking-water contact, so the nipple stays safe when water contains vitamins or medication additives during treatment periods. Farms that retrofit old lines find the big-head clamp gives a noticeably firmer hold than standard clips on slightly worn pipe.

How to Use and Maintain

Press the two yellow wings open, snap the nipple onto the vertical pipe port and confirm it sits square. Flush the whole line with clean water before first use to remove chips and debris. During rearing, walk the line weekly and press each pin to confirm free movement; replace any nipple that drips continuously or feels loose on the pipe.

Fit the nipple at the pipe port and give the yellow wings a firm squeeze until the unit seats; a half-seated nipple will leak around the clamp. Work in good light so each click can be felt and heard.

During the flock, walk the line weekly and press a sample of pins to confirm they spring back. If several nipples feel stiff, flush the whole line to remove sediment rather than replacing units one by one.

Applications

This nipple is designed for broiler and layer farms running automatic push-fit drinking lines on vertical pipe. The big-head clamp is useful on slightly thicker pipe where a standard clip needs extra grip.

It also serves as a replacement part for damaged nipples on existing lines and as a component in new brooder installations. Distributors supply it to farms, integrators and equipment contractors who need a dependable clip-on nipple at a competitive piece price.
