20 mm to 8 mm Variable Pipe Connector

Product Overview

The SL-47 20 mm to 8 mm variable pipe connector is a small injection-moulded orange plastic fitting designed for rabbit drinking systems. Its upper part is an open snap clip that grips a 20 mm main water pipe, while the lower part is a stepped 8 mm barb that pushes into flexible drinking hose. In a typical rabbit cage battery, the main 20 mm water pipe runs along the row, and this connector clamps onto it at each cage position, branching a short 8 mm hose over to the rabbit nipple drinker. The printed dimensions on the product image show a total height of 4.5 cm, a clip jaw height of 1.74 cm and an inner opening width of 2.7 cm, with a piece weight of 6 g.

This connector is an alternative style, meaning it can be clipped onto an existing pipe without cutting the line open. That makes it popular for retrofitting nipple drinkers into older cages, adjusting spacing between drinker stations, or replacing broken fittings during routine maintenance. Because it is lightweight and made entirely of plastic, it does not add noticeable weight to the water pipe and it will not rust inside the drinking line. Farmers can stock it as a low-cost spare part beside nipple drinkers, hose and pipe clips.

Key Features and Benefits

• Snap-on installation - the open clip fits over a 20 mm round pipe by hand, so no tools and no pipe cutting are needed on site.
• Stepped 8 mm barb - the ribbed tail holds flexible drinking hose firmly once pushed in, reducing accidental pulls and leaks.
• Compact size - at 4.5 cm tall and only 6 g per piece, the fitting adds almost no bulk inside the cage pipe run.
• All-plastic construction - no metal parts to corrode in the humid cage environment, and no metal taste transferred into the water.
• Retrofit friendly - works on existing 20 mm lines, allowing new drinker points to be added between old ones.
• Easy spare part - small, cheap and uniform, ideal for bulk stocking on commercial rabbit farms.

Materials and Quality

The connector is moulded from bright orange plastic that stays visible against grey water pipe, making installation and inspection straightforward. The clip body shows a smooth surface with crisp edges, and the barb ribs are evenly formed so the hose grips consistently. Plastic of this type resists the damp, ammonia-rich air found in rabbit houses better than plain iron fittings, which tend to rust and jam. Each piece is checked before shipment, and the bright colour helps stock controllers pick the right fitting quickly during maintenance rounds.

How to Use and Maintain

Press the open clip over the 20 mm pipe at the chosen cage position until it clicks home, then push 8 mm hose onto the barb until seated. When servicing the line, open the clip by hand and pull the hose off to inspect the O-ring seat and clean any algae or feed residue from the barb. If a clip becomes brittle or cracked, replace the whole piece rather than trying to repair it, since the part is low cost compared with a leak that wastes water and damages bedding. Keep spare fittings in a dry bag near the drinking manifold during flock health checks.

Applications

This connector is used in commercial rabbit breeding farms, rabbit cage batteries, small backyard rabbitries and laboratory animal housing where nipple drinkers are fed from a 20 mm main line. It suits both new installations and retrofit work, and it pairs with brass or plastic rabbit nipple drinkers sold in the same product range. Distributors of poultry and small-animal equipment also keep it as a general spare part for drinking-line repairs.

Because it branches 8 mm hose off a 20 mm pipe, it is also handy for custom cage layouts where drinkers must sit at a certain height or offset from the main pipe. Farmers running multiple cage rows can order it in bulk numbers to match the number of drinker points, and mixed container loads allow it to be shipped together with nipple drinkers, hose and pipe clamps.

Frequently Asked Questions

Q1: Does this connector fit my 20 mm water pipe?

The inner opening measures 2.7 cm and is designed as a snap clip for standard 20 mm round drinking pipe commonly used in rabbit and poultry lines. Measure your pipe before ordering if you use a non-standard size.

Q2: What hose size does the tail accept?

The stepped barb is made for 8 mm flexible drinking hose. Push the hose fully onto the ribs for a tight seal; hose clamps are usually not required for this small size.

Q3: Is this fitting made of metal or plastic?

It is an all-plastic orange fitting weighing 6 g per piece. The plastic construction avoids rust in humid rabbit houses and keeps the part light on the pipe.

Q4: Can I retrofit it onto an existing drinking line?

Yes. The open clip style slides over the pipe without cutting the line, which is the main reason this alternative connector is used for adding or replacing drinker points on working cages.
