Graco 15A790 BSPP ½‑Inlet Fitting – Product Overview

Compatible Systems

System / Model Type Description
Graco G‑Series Lubrication Pumps Divider valves and pump manifolds using BSPP inlet thread
Graco Automatic Lubrication Systems (CSP / MSP) Pump-inlet or distribution-valve assemblies requiring ½″ BSPP thread
Graco High‑Pressure Fluid Modules Fluid-handling equipment with parallel pipe thread inlet connection

Product Description

The Graco 15A790 BSPP ½‑Inlet Fitting is a precision-engineered connector designed to provide a secure, leak-resistant fluid inlet for Graco systems that use British Standard Pipe Parallel (BSPP) threads.

This fitting ensures a strong, tight seal while facilitating fluid transfer into pumps or manifolds, making it ideal for industrial lubrication, fluid‑dispensing, or high-pressure systems. Its durable design is suitable for repeated installation and removal, supporting long-term, reliable operation.

Key Features

  • ½″ BSPP inlet thread for secure, pressure-rated connections
  • Sturdy metal construction for high durability and resistance to wear
  • Designed to minimize leaks under high fluid pressures
  • Allows repeatable assembly/disassembly for maintenance or servicing
  • Compatible with Graco lubrication and fluid-distribution systems using BSPP threads

Installation & Maintenance Tips

  • Depressurize the system before installing or removing the fitting.
  • Apply a suitable thread sealant or PTFE tape compatible with BSPP threads.
  • Torque carefully — ensure a tight connection without overtightening.
  • Inspect periodically for signs of wear, thread damage, or leakage.
  • Replace the fitting if thread corrosion, cracking, or seal failure is detected.

Frequently Asked Questions

BSPP threads provide a parallel connection that, when used with proper sealant or an O-ring, can deliver strong sealing performance under high fluid pressure.

It's commonly used in Graco lubrication pumps, divider valves, and fluid systems that require a ½″ BSPP inlet connection.

Use a thread sealant or PTFE tape that is compatible with fluid systems and BSPP threads; ensure the fitting is correctly torqued for a reliable and leak-resistant connection.
