RY-LF-02 Three Outlet Deck Mounted Laboratory Bench Faucet with Gooseneck and Twin Side Outlets

Product Overview

The RY-LF-02 is a deck-mounted laboratory bench faucet carrying three outlets on one body: a tall U-bend gooseneck at the top, and two low-level side outlets on swing arms, each with its own blue indexed knob and a serrated hose nozzle. The whole assembly passes through a single bench cut-out on a round flange. It is intended for benches where one deck position has to serve several jobs — washing glassware at the tall spout, filling a vessel at one low outlet and running a hose from the other — without drilling three separate holes in the bench top.

Why Three Outlets on One Body — and What It Costs

Consolidating outlets onto one deck position saves bench space and cut-outs, and it keeps the plumbing under the bench to one riser. The cost is hydraulic: all three outlets draw from the same supply. Open two at once and the stream at each drops; open all three and the tall gooseneck, which needs the most head, becomes the weakest. On a bench where two people routinely work at the same sink, the supply has to be sized for simultaneous draw, not for one tap at a time — a point that is almost never checked when the bench services are laid out.

The swing arms are the second consideration. They are the moving parts, and their joints are where a lab faucet first weeps. Specifying them is fine; treating them as a fixed spout and forcing them past their travel is what breaks them.

The third point is labelling. Three outlets at one position invite confusion about which one carries what. If the bench supplies cold, tempered and demineralised water to the same body, every outlet must be tagged, and the tags must be readable from the standing position rather than engraved under the sink.

And the standing caution for every faucet in this range: three outlets still make it a tap, not an eyewash. Multiple nozzles do not produce the controlled twin stream at eye height that ANSI Z358.1 requires, and a bench fitted with this body still needs a dedicated flushing point within ten seconds' reach.

Key Features

• Three outlets on a single deck-mounted body: one tall U-bend gooseneck plus two low-level swing outlets.

• One blue indexed knob per outlet, so each stream is controlled independently and can be shut off at the point of use.

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

• White moulded polymer body with a smooth finish that wipes down and resists dilute acids better than a coated metal body.

• Single-hole deck mounting on a round flange, covering the cut-out and spreading load on the bench top.

• Swing arms that reach over a wide sink without a second deck penetration.

• Tall gooseneck gives clearance for graduated cylinders and tall vessels at the centre outlet.

• Low outlets sit close to the sink floor, which reduces splash when filling shallow trays.

• Simple service: knobs, valve seats and nozzles are the only wearing parts, and all three are replaceable without removing the body.

Technical Specifications

Installation and Commissioning

1. Check the bench cut-out and the flange seating before assembly; the flange must sit flat on the bench surface, not on a chamfer.

2. Confirm the swing arms clear the splashback and the sink edges through their full travel before the body is finally tightened.

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

4. Refit the nozzles and test each outlet separately, then test two together and note the drop in stream height at the gooseneck.

5. Set the swing arms so each low outlet reaches its working position without crossing the centre line of the sink.

6. Label each outlet with the service it carries and record the simultaneous-draw performance in the commissioning file.

Operation and Maintenance

Weekly: operate all three knobs through their full travel and check for weeping at the swing joints and at the deck flange.

Monthly: remove the nozzles and clear scale; wipe the body and check that the swing arms still move without stiffness.

Quarterly: inspect the valve seats for wear, check the spout and arms for crazing at the bends, and confirm the outlet labels are legible.

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

Standards and Compliance

This is a laboratory water fitting and is not an emergency eyewash or shower. It does not meet ANSI Z358.1-2014, and three outlets do not substitute for a compliant flushing point: an eyewash requires a controlled twin stream at eye height with hands-free operation. Where the bench falls under a safety audit, the eyewash must be a dedicated unit within ten seconds' reach. The polymer body must be checked against the chemicals handled at the bench, each outlet must be labelled with its service, and where tempered water is supplied the outlet temperature must be limited to protect users from scalding.

Applications

Teaching and research benches, island sinks serving two workers, preparation and washing areas, QC benches and clean utility rooms where one deck position has to supply a tall spout for glassware and low outlets for hoses and shallow vessels.

Ordering

State the model RY-LF-02, the inlet connection size, whether one service or several are supplied to the body, the required arm reach if it differs from standard, and the body material where the bench handles solvents that attack the standard polymer. Confirm the bench cut-out diameter and the available flow at the bench, since three outlets drawing together need more capacity than a single tap. A compliant eyewash must be specified separately if the bench requires one.
