Double Ferrule Compression Fittings

Product catalog summary

General Information
BULK manufactures high-quality compression and pipe fittings designed for reliable tube connections with pressure-tight sealing. These fittings are made from materials that ensure thermal compatibility and corrosion resistance. It is advised to use tubing and fittings of the same material to prevent galvanic corrosion. The pressure rating of the fittings exceeds that of the tubing, which should be selected based on material, wall thickness, and temperature.

Construction Material
All components of BULK compression fittings are made from the same material as the fitting body. Standard materials include AISI 304 and AISI 316 stainless steel, brass, Monel, titanium, Hastelloy, and Inconel.

Pressure and Temperature Rating
The fittings are rated for high working pressures, with specific ratings depending on the tubing material and conditions. De-rating factors should be applied for high-temperature applications.

Assembly and Reassembly Instructions
1. Loosen the nut and fully insert the tubing into the fitting.
2. Tighten the nut one and one-quarter turns.
3. For reassembly, insert the tubing with set ferrules and tighten the nut until a sharp rise in torque is felt.

Safety Guidelines
1. Do not adjust fittings under pressure.
2. Use appropriate lubricants and sealants.
3. Ensure tubing is softer than the fitting material.
4. Contact local distributors for more information.

How to Order
Select the appropriate size and material using the provided tables. Options include metric or inch sizes, thread types, and special executions like thermocouple connectors or oxygen service fittings.

Products Index
The document provides a comprehensive index of available fittings, including male and female connectors, elbows, unions, adapters, and more, with detailed specifications for each type.

Overview: The document provides detailed specifications for double ferrule compression fittings, including both metric and inch measurements. It covers various configurations such as tube-to-tube, tube-to-port, and tube-to-thread connections.

Specifications: The document lists dimensions and part numbers for different fitting types. Key parameters include tube outer diameter (OD), port size, and thread type. Each entry specifies dimensions such as A, B, C, E, F, and G, which likely correspond to fitting dimensions and tolerances.

Product Categories:

Double Ferrule Compression Fittings: Includes both metric and inch OD tube fittings, with configurations for male and female NPT threads.
Tube Closures: Details on metric and inch OD tube closures, specifying dimensions and part numbers.

Key Data Points: The tables provide comprehensive data on fitting dimensions, allowing for precise selection based on application requirements. The part numbers are structured to indicate the fitting type and size, facilitating easy identification and ordering.

Applications: These fittings are typically used in industries requiring secure and leak-proof connections, such as plumbing, gas, and fluid systems.

Product Specifications: The document lists double ferrule compression fittings for both metric and inch OD tubes. Each product is identified by a part number and includes dimensions for various tube sizes.

Materials: The standard material for BULK precision pipe fittings is 316 Stainless Steel. Other available materials include Brass, Monel, Hastelloy, Inconel, and Titanium.

Pressure Ratings: Pressure ratings are provided for both male and female pipe ends, with female ends having lower ratings due to larger thread diameters. Ratings are calculated according to ANSI B 31.1.

Assembly Instructions: To ensure a leak-tight seal, the use of Teflon tape as a pipe thread sealant is recommended. Instructions include cleaning threads, wrapping tape in the direction of the thread spiral, and ensuring no tape overhangs the first thread.

Ordering Information: The document provides a guide on how to order fittings, including specifying pipe size, material, and thread type. Tables are provided for selecting material and thread type suffixes.

Product Index: The document includes an index of various pipe fittings such as hex nipples, reducing nipples, couplings, adapters, elbows, tees, plugs, and caps, each with specific part numbers and dimensions.

Notes: Dimensions are for reference only and subject to change. All dimensions are in millimeters.
