DESCRIPTION
5K231 Spacer Ring / Guide Vane Seal Ring — Goulds J+ / JS+ / GT Series

Pre-formed spacer (guide vane seal) ring used in Goulds J+, JS+, and GT series pumps. Maintains proper spacing and sealing at the guide vane/diffuser interface to support efficient performance after service or rebuilds.

Manufactured to meet original specifications, the 5K231 spacer ring provides a precise fit and dependable performance in demanding environments.

This part is commonly referenced as 5K231 and replaces earlier molded part 5K6, with updated superseding number 5K555. It may also be described as a guide vane seal ring or spacer ring and meets NSF 61 standards for potable water system applications. Fits Goulds J+ and JS+ jet pumps — J5, J7, J10, J15 and the S models — and the full Irri-Gator GT range, where Goulds specifies this ring as 5K6: GT07, GT10, GT15, GT20, GT30 and the three-phase GT073, GT103, GT153, GT203 and GT303.

Working on a Goulds pump? We build complete rebuild kits for Goulds jet and Irri-Gator pumps — this spacer ring together with the shaft seal and the diaphragm, in one part number instead of three.

Pick the kit that matches your pump:
- Goulds J+ / JS+ Repair Kit — J5, J7, J10, J15 and the S models
- Goulds Irri-Gator GT Repair Kit — GT07, GT10, GT15, GT20, GT30 and three-phase GT073 to GT303
Buying the parts separately? While the wet end is apart, replace the shaft seal and matching diaphragm too — the shaft seal is the most common leak source. These pumps take a 5/8″ Type 166 shaft seal, equivalent to Goulds 10K10:
- Standard, clean water — PS-680
- Salt, treated, warm, heavy-use, or commercial — PS-4240 (equivalent to 10K10)
- Also in this rebuild — 5K162 / 5K557 Diaphragm (J-series) or 5K256 / 5K522 Diaphragm (Irri-Gator GT)
