Graco 15B499 FDA Buna‑N 1040 Diaphragm – Product Details & Compatibility
Compatible Machines
The Graco 15B499 FDA Buna‑N 1040 Diaphragm is engineered for use in the check‑chamber of the Graco Husky 1040 (and SaniForce/1040 sanitary models) air‑operated double diaphragm pumps where a Buna‑N elastomer diaphragm is specified. It is suitable for:
- Graco Husky 1040 and sanitary variants requiring FDA‑compliant Buna‑N diaphragms
- Pumps in chemical transfer, coatings, food‑grade or sanitary fluid systems that specify the 1040 series
- Replacement or routine‑service kits to restore diaphragm integrity and sealing performance in AODD pumps
Product Overview
The Graco 15B499 FDA Buna‑N 1040 Diaphragm is a high‑quality OEM diaphragm crafted from Buna‑N (nitrile) elastomer to meet FDA criteria for fluid‑contact elastomers. It is designed for reliability in one of the toughest pump environments — the 1040 series. By replacing the diaphragm with the exact elastomer material and design specified by Graco, you maintain the pump’s intended performance, ensure durable sealing, and minimise the risk of leakage, downtime or incompatibility.
Key Features
- Buna‑N (nitrile) elastomer material meeting food‑grade/FDA elastomer requirements
- OEM‑specified fit for the 1040 series — ensures proper alignment, stroke, sealing and life‑cycle performance
- Engineered to withstand the cycling, pressures and chemical exposure typical of AODD pump operation
- Restores one‑way diaphragmatic pump motion, fluid chamber isolation and back‑flow prevention
- Serves in demanding environments including coatings, chemical transfer, food & beverage, and sanitary processing where FDA compliancy is required

Usage Notes
- Always ensure the pump is fully depressurized and isolated from fluid before removing or installing the diaphragm.
- Inspect the diaphragm bore, pump center section and fluid chamber for signs of wear, corrosion or damage to ensure proper sealing.
- Clean all mating surfaces and install the diaphragm precisely to maintain pump stroke and sealing integrity.
- After installation, perform a dry and wet test cycle to verify correct operation—watch for leaks, pulsation irregularities or diminished flow.
- Replace the diaphragm promptly if you observe cracks, extrusions, permanent deformation or leakage — delayed replacement can lead to more extensive pump service needs.
