House Block Assembly 302981 Good Quality WaterJet Pump Parts

The House Block Assembly 302981 is a precision-engineered core component used in high-pressure Waterjet Cutting Systems, serving as the main structural housing for on/off valve assemblies and high-pressure sealing components. It functions as the foundation that holds and aligns critical internal parts such as the stem, dynamic seals, seat, and backup rings — ensuring stable pressure control and leak-free water delivery under extreme operating conditions.

Manufactured from premium-grade stainless steel, the 302981 house block assembly offers exceptional strength, corrosion resistance, and dimensional stability even under continuous operation at pressures exceeding 60,000 psi (4,137 bar). Each housing is CNC-machined to ultra-tight tolerances to ensure precise alignment of internal valve components, minimizing vibration, wear, and performance loss.

The House Block Assembly 302981 is fully OEM-compatible with major waterjet brands, including KMT, FLOW, BFT, and WSI, and can be installed as a direct replacement part without modification. It’s the perfect choice for restoring or upgrading on/off valves and cutting head systems, providing long-term reliability and consistent performance for industrial waterjet operations.
