975XL / 975XL2
Reduced pressure principle assembly
Match the complete 975XL or 975XL2 label and nominal size. This reviewed map covers 3/4–2 inches; the current parts breakdown separates standard, complete, rubber, and seat kits.
The smaller 1/4–1/2 inch legacy family is outside this reviewed kit map. Do not substitute 975XL3 references or infer compatibility from a retailer title.
Field reference
975XL kit scope: use the component matrix.
Compare the kit columns on page 1 with the exploded drawing on page 2. Kit names alone do not establish which seats, poppets, covers, or tools are included.
| Observation | What it establishes | Next step |
|---|---|---|
| Model suffix | 975XL / XL2 is the family in the linked document. | A 975XL3 listing needs its own documentation. |
| Nominal size | 3/4–1 inch uses RK34; 1 1/4–2 inch uses RK114. | Read the body marking, not the nearby pipe outside diameter. |
| Seats versus other internals | The XLC column lists check and relief-valve seats along with other internals. XLSK is a separate, narrower seat-service kit. | Match the diagnosed components against the correct size column; cover kits are separate references. |
| Damaged body or failed test | Buying a matching reference does not establish a repairable body or passed assembly. | Include diagnosis, retest, and required filing. Continue → |

Two check covers sit above the reduced-pressure zone and relief assembly.

RK34 and RK114 denote different size bands. XLC includes seats plus other internal components; XLSK is a narrower seat-service reference.
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.
