This check valve is for long-block 87k HyperJet intensifiers and is not recommended to use in the standard 87k HyperJet intensifier 020070-1. Please purchase 020077-1 for standard (short-block) Flow 87k HyperJet intensifiers.

Replacement component designed specifically for long-block Flow HyperJet® intensifier systems operating at pressures up to 87,000 psi. This high-pressure housing supports the internal check valve components responsible for regulating water flow during the intensifier's reciprocating cycle.

Important compatibility note: Part 011307-1 is specifically intended for long-block 87K HyperJet intensifiers and is not recommended for standard short-block HyperJet intensifier model 020070-1. Standard short-block systems require check valve body 020077-1. Verify the intensifier configuration before ordering, as these two check valve bodies should not be treated as interchangeable.
