Brass Parts India manufactures and exports precision Brass Ferrules and Brass Olives for compression pipe fittings from Jamnagar, India — serving plumbing product manufacturers, hardware distributors, HVAC component suppliers, and industrial fittings companies in the USA and globally. Our brass olives and ferrules are precision-machined from certified free-machining brass bar (C36000/CW614N/CZ121) and drawn brass tube, delivering consistent dimensions, reliable sealing performance, and the higher strength needed for stainless steel tube, HDPE pipe, and high-pressure applications where softer copper olives are not adequate.
Jamnagar, India — where Brass Parts India is headquartered — is the world’s largest center for brass machining, making it the globally preferred sourcing origin for precision brass compression fitting components. Export pricing: USD 0.05 – USD 1.20 per piece CIF US seaport.
Brass Olives vs Copper Olives – When to Choose Brass
While copper olives (C12200) are traditional for copper tube plumbing, brass olives are the preferred choice when: (1) connecting stainless steel, chrome-plated copper, or brass tube — where a harder olive material provides better grip; (2) higher working pressures (above 35 bar) are involved; (3) the fitting will be disassembled and reassembled multiple times; (4) the connection is in a vibration-prone environment; or (5) the tube OD is at the upper tolerance limit and more aggressive bite is needed. Brass olives are also standard in many European and US industrial compression fitting systems.
Brass Ferrule and Olive Products We Manufacture
Machined Brass Olives from Bar (CNC Turned)
Precision CNC-turned brass olives from C36000 (C3604/CZ121/CW614N) free-machining brass hexagonal or round bar. These machine-turned olives deliver tighter dimensional tolerances (±0.03 mm on OD) than stamped olives, with smoother surface finish and more consistent taper geometry — critical for high-pressure industrial fittings. Available for metric sizes 6 mm to 54 mm and imperial sizes 1/4″ to 2″. Produced to DIN 3861, BS EN 1254-2, and customer drawings.
Stamped Brass Olives from Tube/Pipe
High-volume brass olives stamped and formed from brass tube (CW614N / C36000 drawn tube). More economical than machined olives for standard plumbing compression fitting sizes. Suitable for residential and commercial plumbing, gas, and heating systems where standard tolerance is adequate. Available in 15 mm, 22 mm, 28 mm metric and 1/2″, 3/4″, 1″ imperial as standard stock sizes.
Brass Two-Ferrule Sets (Front and Back Ferrule)
Precision-machined brass front ferrule and back ferrule sets for two-ferrule tube compression fittings (equivalent to Swagelok, Parker A-LOK, Ham-Let, Gyrolok, and similar brands). Manufactured from C36000 brass to exacting dimensional tolerances. Available for tube sizes 1/8″ OD to 1″ OD in imperial and 4 mm to 25 mm in metric. Compatible with standard two-ferrule fitting bodies from all major manufacturers.
Brass Compression Ring Ferrules for HDPE and Plastic Pipe
Brass grab rings and compression ferrules for use with push-fit and compression fittings on HDPE, MDPE (yellow gas pipe), and PEX/CPVC tube. The harder brass material bites reliably into the softer plastic tube OD, creating a permanent seal. Standard sizes 1/2″ to 2″ CTS (copper tube size) and IPS for compatibility with US plastic pipe compression fittings.
Brass Ferrules for Wire Rope and Cable Sleeves
Cylindrical brass ferrule sleeves for swaging and crimping onto wire rope and cable ends — creating eye terminations, dead ends, and thimble loops. Available in 1/16″ to 1/2″ rope diameter in both oval (double-barrel) and round (single) profiles. Used in rigging, fall protection, marine standing rigging, and architectural tension cable systems.
Brass Hose Ferrules for Hydraulic Hose
Brass crimp ferrule sleeves for hydraulic hose assemblies — the outer shell that is crimped over the hose end to lock in the fitting insert. Standard sizes 1/4″ to 2″ hose. Manufactured from C36000 brass tube or deep-drawn brass cup, with standard crimp dimensions to SAE 100R hydraulic hose assembly standards.
Custom Brass Ferrules and Olives to Drawing
Non-standard sizes, special taper angles, grooved profiles, or complex ferrule geometries machined from C36000 brass bar or tube to your exact drawings. CNC turning from 3 mm to 100 mm OD; tolerances to ±0.01 mm. Prototype to production in 3–5 weeks.

Frequently Asked Questions – Brass Ferrules and Olives
Q1: Should I use brass or copper olives for stainless steel tube?
A: Brass olives are strongly preferred for stainless steel tube. Stainless tube is harder and has a smoother OD than copper tube — a soft copper olive may not bite in sufficiently to create a reliable seal and grip. The higher hardness of brass ensures adequate penetration into the stainless tube surface. For instrument-grade stainless tube (316L), use precision CNC-turned brass two-ferrule sets (Swagelok-equivalent) for maximum reliability.
Q2: Are your brass olives compatible with Swagelok fittings?
A: Our two-ferrule sets are dimensionally equivalent to Swagelok-compatible ferrule sets and are manufactured to the same dimensional standards. However, Swagelok branded fittings technically require Swagelok branded ferrules for full warranty coverage. Our ferrules are suitable for equivalent (Swagelok-compatible) fitting bodies from manufacturers like Ham-Let, Parker, Hylok, and others that use the same ferrule dimensions.
Q3: What brass grade is best for gas line compression fittings?
A: For natural gas and LPG compression fittings, CW617N (CZ122 / C37700) is preferred over CW614N (CZ121 / C36000) because its lower lead content (1.6–2.5% vs 2.5–3.5%) gives better resistance to stress corrosion cracking in the presence of ammonia and sulfur compounds that can be present in gas supplies. We supply both grades — specify CW617N for gas line olives.
Q4: What is your MOQ for brass ferrules?
A: Machined (CNC-turned) brass olives: 500 pieces per size for custom; 1,000 pieces for standard sizes. Stamped brass olives: 5,000 pieces per size. Two-ferrule sets (front + back): 500 sets minimum.
