LDI offers other sight plug series which install into a port with tapered pipe threads with different material and construction options.

If the application requires installing the sight plug into a port with SAE straight threads, select from the sight plugs designed for this style port.

When there is no room for a coupling and wall thicknesses are too thin for machining a port, LDI offers sight plug options suitable for these applications.

If the application also requires a reservoir, LDI can assist you by providing an off-the-shelf or customized reservoir to your specifications.
