RY-LF-04 Tall Gooseneck Laboratory Bench Faucet with Two Side Outlets and Blue Knobs

Product Overview

The RY-LF-04 is a deck-mounted laboratory bench faucet built on a raised riser: a tall U-bend gooseneck at the top with a serrated hose nozzle, plus two low-level side outlets on swing arms, each with its own blue indexed knob and nozzle. The white moulded polymer body mounts through a single bench cut-out on a round flange. The tall riser is the reason to choose this body over the standard-height version — it lifts the centre outlet far enough above the bench to fill tall vessels directly, without tipping them under the spout or filling them from a beaker.

What Extra Height Buys — and What It Costs

The benefit is straightforward: graduated cylinders, volumetric flasks, tall beakers and small carboys can stand on the sink floor under the outlet, which removes a step that people otherwise improvise by holding a vessel at an angle. Anything that removes improvising at a wash sink is worth having.

The cost is mechanical. A tall riser is a longer unsupported lever, and every knock to the gooseneck is carried down to the deck flange. On a bench top that is thin, or where the cut-out is oversize, that moment works the flange seating loose and the first sign is water under the bench rather than at the outlet. A tall body therefore wants a bench top of adequate thickness, a flange that actually seats on the surface, and a habit of turning the spout rather than pushing it. It also wants the swing arms kept below the height where they would foul a wall cabinet or a shelf.

The second cost is splash. Water falling further before it hits a vessel or the sink floor aerates more and splashes wider, so the sink needs the depth and the splashback to take it. The third is hose behaviour: a hose pushed onto the tall outlet hangs from a higher point and swings, which pulls on the nozzle; if the bench is used mainly with hoses rather than tall vessels, the standard-height body is the better choice.

The standing caution applies here as it does to every faucet in this range: height does not make it an eyewash. A tall spout cannot hold a controlled twin stream at eye height or stay open hands-free, so the bench still needs a dedicated flushing point within ten seconds' reach.

Key Features

• Raised riser carrying a tall U-bend gooseneck, giving clearance to stand tall vessels on the sink floor.

• Two low-level side outlets on swing arms, each with its own blue indexed knob and serrated nozzle.

• Three independently controlled outlets on one deck position, so the tall spout and the hoses can be used separately.

• Serrated hose nozzles, removable when an open outlet is wanted instead of a hose connection.

• White moulded polymer body with a smooth finish that resists dilute acids and wipes down cleanly.

• Single-hole deck mounting on a round flange that covers the cut-out and spreads the load of the tall riser.

• Low outlets sit close to the sink floor to reduce splash when filling shallow trays.

• Knobs, valve seats and nozzles are the wearing parts and all are replaceable without removing the body.

• One-piece moulded bends with no exposed thread in the wetted path, which keeps scale from anchoring.

Technical Specifications

Installation and Commissioning

1. Check the bench top thickness and the cut-out before assembly; the flange must seat flat, since the tall riser loads it more than a standard body.

2. Confirm the top of the gooseneck clears any wall cabinet or shelf, and that the swing arms pass beneath them through their full travel.

3. Connect the supply and flush with all three outlets open and the nozzles removed so debris cannot lodge in the seats.

4. Stand a tall vessel on the sink floor under the centre outlet and check the outlet clears its rim and that the spout can be turned to it.

5. Test each outlet separately, then two together, and record the drop in stream height at the tall gooseneck.

6. Check the flange for movement after the first full-flow test, and retighten from below if any rock is felt.

Operation and Maintenance

Weekly: operate all three knobs through their full travel and check the deck flange for rocking or seepage.

Monthly: remove the nozzles and clear scale, wipe the body, and check the swing arms and the tall riser for stiffness or movement at the joints.

Quarterly: inspect the valve seats, examine the gooseneck bend for crazing, and check the flange seating from under the bench.

Annually: replace any seat that needs force to shut off, and check the supply shank and bench underside for corrosion or water tracking.

Standards and Compliance

This is a laboratory water fitting, not an emergency eyewash or shower, and it does not meet ANSI Z358.1-2014. A tall spout does not make an outlet suitable for eye flushing: compliance requires a controlled twin stream at eye height with hands-free operation, provided by a dedicated unit within ten seconds' reach. The polymer body must be checked against the chemicals handled at the bench, and where tempered water is supplied the outlet temperature must be limited to protect users from scalding.

Applications

Benches where tall vessels are filled directly — volumetric and graduated glassware, tall beakers, small carboys — in teaching and research labs, preparation and washing areas, QC benches and clean utility rooms with adequate bench thickness and splashback depth.

Ordering

State the model RY-LF-04, the inlet connection size, the required overall height if it differs from standard, whether cold or tempered water is supplied, and the body material where the bench handles solvents that attack the standard polymer. Confirm the bench cut-out diameter, the bench top thickness and the available flow at the bench, since three outlets drawing together need more capacity than a single tap. Specify a compliant eyewash separately if the bench needs one.
