Hunter 332100 PGV Diaphragm Kit for 3/4-Inch and 1-Inch Valves
Product description
If a compatible Hunter sprinkler valve needs a diaphragm replacement, the 332100 kit is designed for that repair. It fits specified 3/4-inch and 1-inch plastic valves, so matching the valve model matters before you start. Replacing a diaphragm addresses a different need than swapping the entire valve. This kit is intended for the former.

The compatibility list is the main buying check. Although the product name and description refer to several valve families, the manufacturer’s description specifically mentions PGV-101G and PGV-101-ASV. If your valve has a different designation, compare it with the full compatibility list rather than assuming every Hunter valve uses this diaphragm. You’ll appreciate it if you have a listed valve and want to replace its diaphragm instead of replacing the complete valve assembly.
Requirements
This is a repair part, not a complete irrigation valve. It is intended for the listed Hunter plastic valve models in 3/4-inch and 1-inch sizes. The double-beaded seal is designed to help the diaphragm seal under pressure, while the captive plunger is intended to stay with the assembly during disassembly. Those details may be useful when opening the valve for a repair, but they do not establish compatibility with models outside the stated list.
Buyer feedback commonly describes the fit as suitable for PGV valves and mentions using the part to address sprinkler-system leaks. Repair experiences are mixed: some buyers describe the replacement as easy, while others report holes developing after a short period of use. That variation is worth bearing in mind, feedback is not a guarantee of how long a replacement will last in a particular system.
How to use it
The listed installation approach is to loosen the valve’s four captive bonnet bolts, remove the old diaphragm, and fit the replacement. The product information describes the process as tool-free and notes that the captive plunger helps prevent loose parts during disassembly. In practical terms, this is a targeted repair for a valve that needs a new diaphragm, rather than a reason by itself to replace the whole valve. Confirm the valve’s model and size before opening it so the replacement you have on hand matches the assembly.
It might not be a great match if your valve model is not listed or if the repair needed is beyond diaphragm replacement. For those situations, a different replacement part or a complete valve repair may be more appropriate, depending on the issue.
Before you decide
Which valves does this kit fit? The listed models are Hunter PGV, SRV, ASV, PRO-ASV, PGV Jar Top, PGV-100G, PGV-101G, PGV-100A, and PGV-101A plastic valves in 3/4-inch and 1-inch sizes.
Does it replace the entire valve? No. It is a diaphragm kit for repairing a compatible valve, not a complete valve assembly.
Are special tools required for installation? The product information describes installation by loosening four captive bonnet bolts and says no special tools are required.
Final verdict
The Hunter 332100 is a focused option when the existing valve is on the compatibility list and the diaphragm is the part that needs replacement. Its stated fit, double-beaded seal, and captive plunger suit a targeted repair rather than a full valve swap. Choose it only after matching the valve model and size, the mixed reports about repair longevity mean the fit alone should not be treated as a promise of lasting results.
