Sight Glass

Description:

Bronze Sight Glasses are cast from bronze alloy. This assures lasting performance and servicability. Available in both "full flow" and "restricted orifice" design. Flow can be viewed through two high impact polycarbonate windows on either side of the sight glass. All models feature male by female thread patterns for easy "in line" installation. The "full flow" design is suitable for system flow verification and the restricted orifice types can used be to simulate system sprinkler head flow which can be viewed through either window.

Installation:

Installation can be made using readily available field tools and materials. Apply a suitable pipe thread sealant to the either the male or female threads. The brass sight glass with the restricted orifice must be installed so the direction of flow is from the female thread to the male thread. This allows the restricted stream to be viewed through the polycarbonate windows. The unrestricted models may be installed in either direction, however, they should be installed consistent with industry standards. The sight glass threads have been machined according to standard iron pipe thread specifications. Installation is similar to other threaded fittings.Caution: Do not over-tighten. Over tightening will cause the sight glass fitting to crack.
