Brass Parts India manufactures and exports precision Copper Ferrules and Copper Olives for compression pipe fittings from Jamnagar, India — supplying plumbing wholesalers, HVAC distributors, industrial pipe fitting manufacturers, and hardware distributors across the USA and worldwide. Our copper olives and ferrules are stamped or machined from certified C12200 DHP copper to exact dimensional standards, providing reliable leak-free seals in compression fittings for copper, stainless steel, and soft plastic tube systems.
A compression olive (also called a compression ring, compression ferrule, or compression insert) is the critical sealing element in a compression fitting — the component that bites into and grips the tube when the compression nut is tightened, creating a permanent, solderless metal-to-tube seal. Export pricing: USD 0.04 – USD 0.80 per piece CIF US seaport.
What Are Copper Olives and Compression Ferrules?
A copper olive (British/Australian/European term) or compression ring / ferrule (US term) is a ring-shaped copper component that fits over the tube between the compression nut and the fitting body. When the nut is tightened, it drives the olive forward and compresses it radially inward, causing it to bite into the outer surface of the tube and form a gas-tight, water-tight metal seal. Copper olives are the standard component in compression fittings for domestic and commercial plumbing, gas installation, HVAC, and industrial tube and pipe connections worldwide.
Types of Copper Ferrules and Olives We Manufacture
Standard Copper Olives for Compression Fittings (Metric)
Metric compression olives must match the actual tube outside diameter and the fitting’s cone, nut and olive geometry. ASTM B88 nominal water-tube sizes and EN metric tube sizes are not interchangeable size series. Confirm compatibility with the complete fitting design rather than assuming interchangeability between brands.
Imperial Copper Olives for Compression Fittings (Inch)
For inch-size connections, specify the actual tube outside diameter and the required compression-fitting design. ASME B16.26 covers cast copper-alloy fittings for flared copper tubes; it is not a generic dimensional standard for compression olives.
Copper Ferrules for Two-Ferrule Compression Fittings (Swagelok/Parker Type)
Front ferrule and back ferrule sets for two-ferrule tube fittings (equivalent to Swagelok, Parker A-LOK, and equivalent brands) in copper. Front (leading) ferrule: tapered for primary seal and tube grip. Back (trailing) ferrule: provides driving force and secondary seal. Used in laboratory instrument piping, analytical instrumentation, and industrial process tubing in small diameters (1/8″ to 1″).
Copper Flare Ferrules
Compression olives and flare fittings seal by different mechanisms. A conventional flare joint seals on the formed tube flare, while a compression olive deforms within its matching fitting. Use a sleeve or support insert only when specified for that fitting and tube system.
Copper Olive Rings for Radiator and Heating System Fittings
Copper olives for central heating and hot water radiator valve compression connections (15 mm, 22 mm, 28 mm metric and 1/2″, 3/4″, 1″ imperial). Compatible with all standard UK and European radiator valves. The most commonly replaced plumbing component in UK, Irish, and Australian heating systems — a key export product for Brass Parts India.
Thick-Wall Copper Olives for Gas Fittings
Heavier-section copper olives for gas pipe compression fittings — designed to withstand higher gas line pressures (up to 5 bar) and meet BS 6891 (gas installation) requirements. Thicker barrel wall and slightly different taper angle vs standard plumbing olives — not interchangeable. Available in 15 mm, 22 mm, and 28 mm for UK/AUS/NZ markets; 1/2″ and 3/4″ for US gas line applications.
Custom Copper Ferrules and Olives to Drawing
Non-standard OD/ID, special taper angles, or unusual profile shapes machined from C12200 copper rod or stamped from copper strip to your exact dimensions. Used by specialty fitting manufacturers and OEM plumbing product companies.

Frequently Asked Questions – Copper Ferrules and Olives
Q1: What is the difference between a copper olive and a brass olive?
A: Copper olives (C12200 DHP) are softer, more ductile, and provide a better seal on soft copper tube — they deform more easily and grip the tube surface reliably. Brass olives (C37700 or similar) are harder and stronger — preferred for use with harder tube materials (stainless steel, harder copper alloys) or higher-pressure applications. For standard domestic copper plumbing, copper olives are the traditional and preferred choice; many UK and Australian plumbers prefer copper olives for their “forgiveness” and easy disassembly.
Q2: Why use C12200 DHP copper rather than C11000 ETP for olives?
A: C12200 (DHP — Deoxidized High Phosphorus) is the standard copper for plumbing fittings and olives because it has been deoxidized with phosphorus, eliminating the oxygen that causes hydrogen embrittlement during soldering and brazing operations nearby. ETP copper (C11000) contains dissolved oxygen which can cause embrittlement if the fitting is later soldered or brazed in close proximity. For pure compression (no-solder) olives, C11000 is technically adequate but C12200 is the industry-standard specification.
Q3: Are your copper olives compatible with SharkBite, Conex, or Swagelok fittings?
A: SharkBite push-to-connect fittings do not use compression olives — they use an internal grab ring. For Conex, Yorkshire, Pegler, and similar compression fittings, our metric copper olives are dimensionally compatible and meet the same BS EN 1254-2 / BS 864 standards. For Swagelok-equivalent two-ferrule fittings, please specify the tube OD and wall thickness so we can confirm compatibility.
Q4: What is your MOQ for copper olives?
A: Standard sizes (15 mm, 22 mm, 28 mm, 1/2″, 3/4″): 10,000 pieces per size. Non-standard or custom sizes: 5,000 pieces minimum. Assortment packs and mixed-size bags available for distributor customers.
