Our model L flange is the safest, most user friendly ASME B16.5 flanged sight glass available. These use our proprietary sidewall seals that avoid surface compression of glass altogether. It is virtually impossible to crush the glass by over-torquing the flange bolts in our model L, and it is completely safe to re-seal the window by applying additional flange bolt torque. This model is excellent for high temperature and high pressure applications, along with those involving frequent temperature swings to maximum rated temperatures. If you need custom or special options, or even higher temperature and pressure ratings, please ask for a quote.

Simple, safe and economical are the hallmarks of the Model L Flange sight glass from Pressure Products. The Model L features a better seal and lower maintenance needs than competing sight glasses. Rated for temperatures up to 450°F and pressures ranging from full vacuum to 150psi (higher pressures possible for custom configurations), the Model L is an ideal choice for applications using standard ASME B16.5 CL150 (2" to 8") flange connections.

The Model L is designed so that none of its metal parts (either carbon steel or stainless steel) are in contact with the process fluid, and no mating gaskets are required. Only the seal, bottom cushion gasket and lens are wetted parts. Seals are available in Silicone, VitonⓇ, or TeflonⓇ.

Model L Flange sight glasses can also be manufactured to DIN standards or non-ASME flange mounts upon request. Other popular options include PTFE coated glass and rotating window wipers. Request a quote for these custom options.
