Product Overview
The 15H302 Fitting Reducer 1‑3/16 SAE x 1/2 NPT is a precision‑machined adapter fitting built to connect different sized ports within Graco fluid systems. Specifically engineered for reduction from a large SAE‑style male coupling (1‑3/16″) down to a 1/2″ NPT female port, this fitting ensures proper thread engagement, sealing and pressure containment. Whether used during retrofit, repair or system reconfiguration, it maintains system integrity and supports correct fluid path sizing.
Constructed to OEM specification, this fitting ensures compatibility, leak‑free operation and safe performance under pressure. Ideal for professionals modifying or servicing industrial spray, foam or coating equipment where port sizes differ.

Installation & Usage Tips
- Ensure system is depressurised before removing existing fittings.
- Clean threads and sealing surfaces to remove old thread‑sealants or debris.
- Install the 15H302 reducer fitting into the correct port, apply appropriate thread sealant if specified by OEM, and torque to specification.
- Test the system at low pressure initially, inspect for leaks and proper fluid path before returning to full operation.
- During future service intervals check for thread corrosion or signs of leak path formation; replace the fitting if any compromise is found.
