Brass Nipples

Avoiding thread mismatches and length limitations often leads to frequent replacements and poor fit during integration. Our Brass Nipples eliminate these issues by offering multiple thread types, flexible lengths, and seamless fit control.

Nominal Size(s)

1/8″ to 2″ (NPT, BSPT, BSPP, Metric)

Thread Type(s)

NPT (Tapered), BSPT (Tapered), BSPP (Parallel), Metric (Parallel)

Overall Length

1″ to 12″ (Standard) / Custom lengths up to 24″ available

Nipple Type/Configuration

Close, Hex, Barrel, Swaged, Reducing, Straight, Hose

Material Grade

C36000 (Free-Cutting Brass), CW617N (EN), C37700 (High-Strength)

Product Description

You can choose from a range of nipple types, from close and hex to reducing and swaged, based on your system’s space and port depth. Every unit is machined to meet thread pitch, wall thickness, and flow diameter expectations for pressure-sensitive or fluid-critical applications.

Pressure Rating

150 PSI to 1000 PSI (10.3 to 69 bar) (size/wall-dependent)

Temperature Range

-65°F to 400°F (-54°C to 204°C)

Connection Type

Male-Male (MxM), Male-Female (MxF), Female-Female (FxF)

Thread Engagement Length

0.25″ to 1.5″ (taper-dependent for NPT/BSPT)

Internal Flow Diameter

0.15″ to 1.75″ (varies by size and configuration)

External Diameter

0.25″ to 2.25″ (varies by size and nipple type)

Finish/Coating

Natural Brass, Electroless Nickel (ENP), Chrome, Anti-Corrosive Coating

Standards Compliance

ASME B1.20.1, ISO 228, DIN 7604, ANSI B16.11, ASTM B16

Weight

0.05 lb to 5 lb (size/length-dependent)

Wall Thickness

0.08″ to 0.35″ (reinforced for high-pressure applications)

Thread Pitch

14 TPI (1/8″ NPT) to 8 TPI (2″ NPT) / Metric pitches available (e.g., M12x1.75)

Technical Advantages

Thread profiles follow the exact standards of ASME B1.20.1, ISO 228, and DIN 7604, ensuring leak-proof fits in global systems. We support wall thickness from 0.08 inch to 0.35 inch, covering both low-pressure lines and reinforced setups. With internal flow diameters up to 1.75 inch, there’s no need for extra adapters or reducers for throughput control. Electroplated coatings extend life in exposed or semi-corrosive areas while keeping all mechanical values consistent.

Industry Applications

Instrumentation Panels

Brass Nipples deliver tight seal connections between gauges, valves, and regulators where threaded alignment and vibration resistance are critical.

HVAC and Refrigeration

Used for refrigerant lines and drainage ports, they handle pressure and temperature cycles without thread fatigue or wall failure.

Compressed Air Systems

Ideal for compressor outlets, tool lines, and regulators, offering secure thread grip and zero air leakage in high-duty cycles.

Hydraulic Control Circuits

Barrel and swaged types suit directional valves and compact manifolds, ensuring minimal restriction and tight fluid control.

Automated Wash Stations

Installed for connecting nozzles, spray bars, or booster lines, especially where corrosion resistance and ease of threading matter.

Food Grade Utility Piping

Electroless nickel or chrome-coated variants resist sanitizing agents, making them fit for CIP lines and auxiliary fluid paths.

Custom Fit for Systems that Vary

No two assembly environments use the same thread standards or pressure values, and we build for that variability. From mixed connection types to swaged reducers and high-flow straight types, we manufacture to fit the required footprint and function.

If you deal with long runs, pressure changes, or part interchangeability, our support for up to 24 inch custom lengths helps avoid sourcing from multiple vendors. You receive a part that arrives thread-ready, fit-for-pressure, and compatible with your existing layout.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

Can you match our thread standards across different international systems in one batch?

Yes, we can manufacture mixed batches with NPT, BSPT, BSPP, or Metric threads as per your assembly layout. Each unit is machined separately to meet exact pitch and taper requirements for its specified region. This avoids downstream re-threading or adapter use during system installation.

We use odd-length runs. Can Frigate manufacture custom nipple lengths beyond standard sizing?

Yes, we offer custom lengths up to 24 inches based on your application fit. You can define the exact length down to quarter-inch tolerance for close or staggered connections. This removes the need for on-site adjustments or multiple short connections.

Can we choose the internal diameter or wall thickness to suit high-flow or high-pressure needs?

Yes, you can define internal flow diameter and wall thickness during the enquiry stage. We adjust bore size and outer diameter depending on pressure range or flow rate needed. This ensures compatibility with pumps, valves, or reducers without causing velocity loss.

We want specific connection combinations like Male-Female or Female-Female. Can that be done?

Yes, we support Male-Male, Male-Female, and Female-Female threads in all configurations. You can also choose from hex, swaged, or reducing types based on space and port style. This gives full flexibility while connecting dissimilar components across your equipment.

Can we get coated finishes to resist washdowns or corrosive vapors?

Yes, we offer electroless nickel, chrome, and anti-corrosive coatings upon request. These finishes improve surface durability and reduce maintenance in exposed environments. Let us know the working conditions, and we will recommend the suitable finish option.
