RY-EA-PA1 Stainless Steel Eyewash Combination Pipe Fitting with Tee, Cross Arm and Bent Tube

RY-EA-PA1 Stainless Steel Eyewash Combination Pipe Fitting with Tee, Cross Arm and Bent Tube

Product Overview

The RY-EA-PA1 is a one-piece stainless steel pipe fitting for an eyewash station: a vertical tee body with a threaded port, a horizontal cross arm, a leg ending in a flared foot, and a bent tube with an external thread at its free end. It replaces a stack of separate tees, elbows and nipples in the section of pipework that carries water from the supply to the eyewash head and bowl. Because the geometry is formed in one piece rather than assembled from fittings, the head ends up where the drawing says it should be, and there are fewer screwed joints to weep.

Why One Piece Beats a Stack of Fittings

On paper, a tee, two elbows, a nipple and a bent tube do the same job. In service they behave differently, and the difference shows up in two places.

Joints are where water finds a way out. Every screwed joint on an eyewash line is a potential weep, and a station is a wet place: it is tested weekly, it stands in wash-down areas, and the water in it is often warm. A fitting that replaces four or five joints with one formed body removes those leaks from the maintenance list. That is the strongest argument for this part, and it is why stations that are rebuilt rather than patched often come back with a one-piece assembly.

Geometry holds the aim. A stack of fittings can be assembled with each elbow turned a little differently, and the result still works — but the nozzle then points somewhere other than where it was designed to point, and the assembly can creep round under vibration or when someone leans on it. A one-piece fitting fixes the relationship between the supply, the bowl and the nozzle. What it cannot do is adjust: if the arm length or the drop to the bowl does not match the station, there is nothing to shim, so the part has to be ordered to dimension rather than made to fit on site.

Inside the fitting is as important as outside. A formed body has internal welds or, if cast, internal surfaces that are harder to inspect than the bore of a plain tube. Weld spatter and casting sand left inside will travel to the nozzle and block it, and the blockage will appear days after the installation, not at commissioning. The assembly should be flushed through before the nozzle is fitted, and the water should be caught and looked at.

The flared foot and the threaded port do the sealing. The foot seats against a bowl or column face, and it seals only if that face is flat and clean; a distorted mating face will weep no matter how tight the joint is. The threaded port takes the supply connection, and the external thread at the end of the bent tube takes the nozzle or a short hose — so the thread form and size at each end have to be confirmed, not assumed, when the part is ordered as a spare.

Key Features

• One-piece stainless steel body combining a tee, a cross arm, a flared leg and a bent tube.

• Replaces several screwed fittings, removing joints that would otherwise weep in a wet station.

• Fixed geometry that keeps the nozzle aimed where the station was designed to deliver water.

• Threaded port for the supply connection and an external thread at the tube end for the nozzle.

• Flared foot that seats against the bowl or column face for a face-to-face seal.

• Stainless steel throughout, with no plated components to rust at the joints.

• Substantial wall section that resists deformation if the station is knocked.

• Simple part with no moving components and nothing to adjust or wear out.

• Individual packing, suitable for spare-part stock.

Technical Specifications

Fitting

1. Isolate the station supply, lock the valve off and drain the line before removing the old pipework.

2. Check the fitting against the station drawing — arm length, drop and port positions — before any sealant is applied; a one-piece part cannot be adjusted afterwards.

3. Clean both sealing faces and check them for flatness and burrs; a distorted bowl face will weep regardless of joint tightness.

4. Fit with the correct sealant or washer for potable-quality water and tighten to the threads, supporting the body so the joint is not loaded by the arm.

5. Flush through before fitting the nozzle, catching the water so any weld or casting residue is seen rather than left in the line.

6. Fit the nozzle, restore the supply and check the aim and the flow; then check every joint on the assembly for weeping.

Maintenance and Inspection

Weekly: operate the station for at least three minutes and check both joints and the flared foot for weeping.

Monthly: check the assembly is still rigid, that the arm has not been bent, and that the nozzle is still aimed correctly.

Quarterly: inspect the welds and the flared foot for staining or pitting; check the threads at the port and the tube end.

Annually: check the inside of the tube for scale build-up if flow has fallen, and replace the assembly if a weld has cracked or the flared foot no longer seats.

Standards and Compliance

This fitting is a component of an emergency eyewash; the installed station must meet ANSI Z358.1-2014 in full — fifteen minutes of flushing with tepid water at 20–37 °C, hands-free activation, nozzles at the required height above the floor and clearance from the wall, unobstructed access within ten seconds of the hazard, and a controlled twin stream at a velocity the casualty can tolerate. The fitting contributes to that by holding the nozzle in its designed position; a station whose arm has been bent or rotated no longer delivers water where it was commissioned to deliver it. Materials and thread sealants must be suitable for potable-quality water where the line serves an eyewash.

Applications

Replacement of corroded or weeping tee-and-elbow assemblies on eyewash stations, rebuilds where the bowl and head are sound but the pipework has been patched repeatedly, new stations built from components, and spare-part stock for maintenance teams.

Ordering

State the model RY-EA-PA1, the port and tube-end thread sizes and forms, the arm length and drop required, and whether stainless 316 is needed for a coastal or chloride-rich site. Supply the station make and model, or the dimensions taken from the old part, since this is a fixed-geometry fitting and cannot be adjusted on site. Confirm whether the mating bowl face is flat before ordering, so a damaged face can be dealt with at the same time.
