Nickel-Plated Brass Fittings:
Pro-Fit
®
, Standard NPTF & Coated Threads
Features
Collet
• Nickel-Plated, All-metal Collet and Release ring
• Collet design offers greater grip strength under higher
pressure or tubing tension
• Collet release mechanism based on relaxed slope of grip
teeth, as opposed to disengaging “bite-rings” from partially
cut tubes
• Removable Collet and tube o-rings
Body
• All-Metal, Nickel-Plated body and Threads
• Compact Brass bodies from Brass forgings
• Standard Buna-N or Specialized O-ring choices for High-
Temp, Low-Temp, Special Fluids, Food-Grade compatibility
• Broad Range of shapes and configurations
• Crimp design on Swivels maintains Full ID Flow path
• Swivels offer Mechanical crimping lock based on cold-forged
brass and not spin-swaged or “thinned” brass
• Full ID Flow for Swivels and Straights, with high relief on
larger sizes
• Internal Hex on Straight fittings

Thread Design
• Low Profile Fit
• Fast Installation
• Perfect Reusable Seal
Benefits
Collet
• Won’t break like plastic release rings and bodies; More Durable
design
• Higher holding force, with easier release
• Won’t scratch tubes like “bite-ring” designs
• Less chance of micro-leakage and bubble-leaks over time due to
damaged tubing
• Higher pressures actually offer greater grip-strength with high-
pressure Nylon tubing
• OD Tube Size stamped on Collet face
Body
• Resistant to UV exposure
• Better resistance to stress-cracking, abrasion, solvents,
detergents, hydrocarbons and other fluid media
• FDA/NSF approved materials, ( Including customized Nickel-
Plating and o-ring options)
• Simplified manifold circuits with broader variety of fitting
combinations and shapes to select
• Lighter weight for End-of-Arm tooling & Robotic handling,
• Compact design reduces overall dimensions for valve
assemblies, packaging applications and control cabinets
• 12% Reduction in overall Body size, compared to previous Brass
line
• Full ID Flow and high relief undercuts offers greatest flow without
restriction to circuit design flow calculations
Pro-Fit®
Thread Design
• Eliminates exposed threads and fits into tight spaces, making
them ideal for food processing and hygienic applications.
• Eliminates the need for Teflon® tape or pipe dope. Shorter
thread length requires fewer turns to tighten.
• The captured Teflon® sealing ring provides a dependable
and reusable shoulder seal without the risk of thread sealant
contamination.
