A damaged union or failed sight glass can turn a simple service issue into recurring leaks and make troubleshooting flow through the filter system harder than it should be.\u003c\/p\u003e\u003cp\u003eThis union kit is used on Raypak Protege RPSF systems and includes a sight glass for visual inspection of flow through the connection point. When the union body is worn, the seal surfaces are damaged, or the sight glass is compromised, the assembly can leak or lose its usefulness during maintenance. Replacing it restores the connection and gives you a direct visual reference at the system union.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eUnion connection is leaking or no longer tightening correctly\u003c\/li\u003e\n\u003cli\u003eSight glass is cracked, cloudy, or damaged\u003c\/li\u003e\n\u003cli\u003eService work requires replacement of the connection assembly\u003c\/li\u003e\n\u003cli\u003eFilter-side troubleshooting is harder without a usable visual flow point\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat this part does:\u003c\/strong\u003e It provides the union connection and integrated sight glass used on the compatible Protege RPSF assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for Raypak Protege RPSF systems.
