LSP1351 Series Fused High Pressure Sight Plug - SAE Straight Thread
Additional Product Information
The LSP1351 Series fused high pressure steel sight plug has a clear glass sight and male SAE straight thread connection. The fused, one-piece construction allows for higher operating pressures. The sight plug can be accessorized with reflector and float ball. The material choice for o-ring tank seal typically determines the operating temperature range for this series sight plug. Box quantities may apply.

The LSP1301 Series sight plugs also install into ports with SAE straight threads, but offer different material, construction and performance options.
If the application requires installing the sight plug into a port with tapered pipe threads, LDI offers the following series of 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.
