OIL REGULATOR ADAPTER KITS

Applications

Due to various compressor sight glass configurations, Henry Technologies

offers several adapter kits to install Oil Level Regulators. The Standard

Adapter Kit (3-033-201) is included with all Mechanical and Electro-

Mechanical Oil Level Regulators. Included in the 3-033-201 kit is (2) O-

Rings, one Quad Ring, Bolts, and Nuts. All adapters with sight glass patterns

different from 3 Bolt 1-7/8” BC also include the standard adapter kit. Oil

Regulators Adapter Kits are suitable for use with HFC and HCFC refrigerants

and their associated oils, as well as other industrial fluids non-corrosive to

steel, copper, and synthetic rubber.

Materials of Construction

Although construction varies, all adapters are made from carbon steel. The

O-Rings are made of Neoprene and hardware is made from Grade 5 Steel.

The function of an Oil Regulator Adapter Kit is to allow Mechanical,

Electro-Mechanical, and Optronic Oil Level Regulators to be

installed on most popular compressor models.

Installation - Notes

1. Do NOT operate ANY Oil Level Regulator at 1/4 sight glass when using

an adapter with an inside diameter smaller than the Oil Level Regulator

flange port.

2. Oil Level Regulator installation should follow requirements of compressor

manufacturers where applicable.

3. Full Instructions are provided in the Product Instruction Sheet included

with each Adapter Kit.
