SKU 24M504 is literally named for an NVH (noise/vibration/harshness) foam system — automotive body-cavity acoustic foam, so the tie is at part-number level not market-list level. Static/dynamic/impingement mixing options, positive displacement pump tech, Elite construction option. HFR is the only hydraulic drive and the highest-minimum-shot platform (30cc per Graco's own comparison). Manuals 313997EN, 313998EN, 3A0235EN-J, 348782EN-A.

Real Specifications
| NVH Foam System SKU | 24M504 — Hydraulic Fixed Ratio, 160/160, Carbon Steel | graco-sealants-adhesives.md |
| 1:1 Ratio SKU | HFRSA1 — Hydraulic Fixed Ratio System, 1:1 ratio, Carbon Steel | graco-sealants-adhesives.md |
| Ratio range (comparison table) | 1:1 to 32:1 | graco-sealants-adhesives.md |
| Minimum shot size (comparison table) | 30cc — the highest minimum shot size of the 4 platforms Graco compares (PD44, PR70, EFR, HFR) | graco-sealants-adhesives.md |
| Mixing options | Static, dynamic, or impingement mixing | graco-sealants-adhesives.md |
HFR is the only hydraulic-drive platform in Graco's own comparison table and carries the highest minimum shot size (30cc) of the four compared — specifying it below that volume, where a lower-cost pneumatic/servo drive already covers the range, is an oversized fit.
SKU 24M504 is literally named for an NVH foam system — automotive body-cavity acoustic foam — so the automotive tie here is at the part-number level, not a marketing category. HFR's 30cc minimum shot and hydraulic drive are the right call when volume genuinely exceeds what PR70 or EFR can deliver; specifying it below that threshold is buying capacity the application doesn't use.
