Please verify your filter's model number against each part number (CX900G, ECX1322A, ECX271261) before ordering to ensure compatibility.\u003c\/p\u003e\n\u003ch4\u003eQ: What does the pressure gauge's glycerin fill do?\u003c\/h4\u003e\n\u003cp\u003eA: The glycerin fill in the ECX271261 Boxed Pressure Gauge dampens pointer movement caused by water pressure fluctuations and vibration. This keeps the needle steady for easy, accurate readings and helps protect the internal mechanism for long-term durability.\u003c\/p\u003e\n\u003ch4\u003eQ: Is Teflon tape necessary for installing the pressure gauge?\u003c\/h4\u003e\n\u003cp\u003eA: Yes — wrapping Teflon tape around the threaded connection before installing the pressure gauge creates a watertight seal and prevents leaks. The tape is included in this kit for your convenience.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I know when my cartridge filter needs servicing?\u003c\/h4\u003e\n\u003cp\u003eA: The ECX271261 Pressure Gauge features two settable indicator needles. Set one needle at your clean filter pressure baseline and the other at your cleaning threshold (typically 8–10 PSI above baseline). When the live reading reaches the second needle, it's time to clean or inspect your cartridge filter.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Which pool filter models are compatible with this Star-Clear Plus replacement kit?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This kit — including the CX900G Knob, ECX1322A Directional Vent Valve, and ECX271261 Boxed Pressure Gauge — is designed for use with Star-Clear Plus cartridge filter systems.
