Graco 15C332 1/4 NPT × 1/4 BSPP Nipple Fitting
The Graco 15C332 nipple fitting is engineered to facilitate secure, transition‑type connections between 1/4‑inch NPT (National Pipe Thread‑Taper) and 1/4‑inch BSPP (British Standard Pipe Parallel) ports. This specialized adapter is ideal in fluid systems where compatibility between differing thread standards must be maintained without compromising sealing integrity or system reliability.
Compatible Machines
- Graco high‑pressure fluid systems requiring mixed‑thread adapters
- Graco proportioning, spray, or pump systems where one port is NPT and the mating port is BSPP
- Graco process and finishing equipment in global installations where regional standard threads change
Key Features
- Transition nipple from 1/4 NPT male to 1/4 BSPP male — bridging two thread standards
- Durable metal construction for robust performance in high‑use environments
- Precision‑machined threads to ensure tight fit and leak‑resistant performance
- Compact form factor for installation in tight spaces and system retrofits
- Designed for ease‑of‑integration into existing Graco systems requiring standard‑to‑standard adapters
Benefits
- Eliminates the need for complex work‑around plumbing when connecting different thread standards
- Reduces downtime by providing a genuine Graco adapter that fits seamlessly into systems
- Minimizes risk of leaks or system failure by using a purpose‑built nipple fitting rather than makeshift adapters
- Simplifies global servicing and inventory by standardizing on one genuine part for mixed‑thread connections

Installation Tips
- Ensure both mating ports (NPT and BSPP) are clean and free of debris or old sealant residue.
- Apply appropriate thread sealant or tape as recommended for your fluid type and system pressure.
- Hand‑start the threads carefully to avoid cross‑threading; then torque snugly per system requirements.
- After installation, verify for leaks under system pressure before full operation.
- In global systems where both NPT and BSPP are used, label the adapter location for future maintenance clarity.
Why Choose the 15C332?
