Verified model passport / Zurn Wilkins
975XL / 975XL2
Reduced pressure principle assembly
The 975XL and 975XL2 share repair-kit families, but the part-number prefix changes by size band. Confirm the body label and nominal size before selecting a kit.
Zurn marks the 1/4–1/2 inch 975XL product page as discontinued while continuing to publish official repair parts. Verify the exact body label and current replacement status.

Identity check
Confirm this model before ordering.
Similar-looking assemblies can use different internals. A search result or pipe size alone is not enough.
- 01
The model marking may read 975XL or 975XL2; do not substitute 975XL3 data.
- 02
Two check covers sit above the reduced-pressure zone and relief assembly.
- 03
Kit prefixes RK14, RK34, and RK114 correspond to the published size bands, not a universal kit.
Before return to service
A matching kit is not a passed assembly.
Stop for body damage. Cracks, distortion, severe corrosion, or freeze damage can move the job from internal service to replacement.
Test after repair. Where the assembly is regulated, the governing utility or authority decides tester approval, reporting, and deadlines.
Use the current instructions. Part references can change. Confirm availability and supersession with the manufacturer or an authorized supplier.
