Masterflex Tubing

Updated: 2026-07-18

Overview

Masterflex hoses are precision-engineered flexible tubing systems designed for critical fluid handling applications. Manufactured by Cole-Parmer, these hoses are trusted in industries requiring reliable performance under challenging conditions. They are available in various materials, including PharMed® BPT for biocompatibility and Chemfluor® for extreme chemical resistance. The product line includes peristaltic pump tubing, reinforced hoses, and multi-layer constructions tailored to specific industrial or laboratory needs. Their modular design allows integration with Masterflex pump systems or standalone use with standard fittings.

Structure and Working Principle

Masterflex hoses typically feature a multi-layer construction combining flexibility with structural integrity. For example, PharMed® tubing has a three-layer design with a smooth inner bore to minimize fluid retention, while reinforced variants incorporate braided polyester for high-pressure applications. In peristaltic pump systems, the hose's elasticity enables precise fluid displacement through compression by rollers, ensuring contamination-free transfer. The materials are selected to withstand repeated flexing without cracking or deformation, even with abrasive or viscous fluids.

Key Features

Chemical resistance is a hallmark of Masterflex hoses, with options resistant to acids, solvents, and aggressive media. Fluoropolymer-based hoses can handle concentrated sulfuric acid, while silicone variants suit ultra-pure applications. Temperature tolerance ranges from -100°C to +200°C depending on material. Other features include USP Class VI and FDA compliance for medical/food use, anti-kink designs for uninterrupted flow, and color-coding for easy identification. Some models offer low gas permeability or static-dissipative properties for specialized processes.

Application Areas

These hoses are indispensable in pharmaceutical manufacturing for sterile fluid transfer, particularly in bioprocessing where leachables must be minimized. The food industry uses FDA-approved grades for ingredients like dairy or oils, while chemical plants rely on corrosion-resistant models for acid handling. Laboratories deploy Masterflex tubing in analytical instruments, autoclaves, and environmental testing equipment. Emerging applications include semiconductor wet processing and renewable energy systems, where material purity and durability are critical.

Maintenance and Precautions

Regular inspection for wear, discoloration, or swelling is recommended, especially in peristaltic applications where internal degradation may not be visible. Replace hoses showing reduced flexibility or surface cracks. Clean with compatible solvents—avoid abrasive cleaners that could damage the inner lumen. For pressurized systems, always verify the hose’s pressure rating and use proper clamps/fittings. Store coiled hoses away from direct sunlight or ozone sources to prevent premature aging. Material Safety Data Sheets (MSDS) should be consulted for chemical exposure limits.

B2B Procurement Guide

Bulk purchases often qualify for volume discounts—negotiate pricing for orders exceeding 100 meters. Specify requirements like inner/outer diameter (standard sizes: 1/8" to 1"), length tolerances, and certification needs (e.g., 3-A sanitary standards for food). Leading distributors include Cole-Parmer, VWR, and specialty fluid-handling suppliers. Request samples for material compatibility testing before large orders. For custom configurations (e.g., pre-assembled fittings), lead times may extend to 4–6 weeks. Consider total cost of ownership, including replacement frequency in your ROI calculations.
