  Hose fittings - Hydraulok
Overview
Hydraulok hose fittings, a line of permanently attached hose
fittings from Fittings Corp., are available for use with
medium pressure hydraulic, Teflon, thermoplastic, and metal
hose. Hydraulok fittings are attached by means of swaging,
crimping or welding. For ease in finding the fitting solution for
your needs, Hydraulok hose fittings are broken in to four
categories: Hydraulic, Teflon, Thermoplastic and Metal.
Hydraulic
Hydraulok hydraulic fittings are one piece fittings manufactured from SS 316 stainless steel. They are designed to work with SAE 100R1AT, SAE 100R2AT, and SAE 100R16 hydraulic hose, in a range of operating conditions. The design features deep tapped inner threads in the collar that grip the outer rubber cover of the hose when the fitting is correctly attached to the hose. The short collar design combined with the rigid insert allows for a clean single crimp finish.
Hydraulic Hydraulok fittings are durable and dependable corrosion resistant fittings often used in marine, oil, gas, critical application and defense industries.
Specifications & Operating Parameters
Standards & Approvals
SAE J516 & J517
Pressures
Medium. Up to 3,000 psi depending on hose construction and fitting configuration.
Temperatures (limiting by the composition of the hose)
Nitrile/Buna-N from –30 to 250°F
Vibration
Medium to High. Depending on end fitting connection.
 
Teflon
Hydraulok Teflon hose fittings are two piece fittings manufactured from 300 series stainless steel. They are designed to work with SAE 100R14 and MIL-H-27267 hose in an extensive range of temperatures and applications. The short collar design assures ease of hose insertion for quick and efficient assemblies. The collar slides over the stainless steel outer braid of the hose while the insert supports the soft Teflon inner tube. The crimping/swaging action secures the hose between the collar and the insert to create a clean finish.
Hydraulok Teflon Hose fittings are designed for higher purity or temperature environments and water-, synthetic- and petroleum based hydraulic fluid applications.
Specifications & Operating Parameters
Standards & Approvals
SAE J517
Pressures
Medium. Up to 1,500 psi (per SAE J517) or higher depending on hose construction and fitting configuration.
Temperatures (limiting by the composition of the hose)
PTFE/Teflon from –100° to 450°F
Vibration
Medium to High. Depending on end fitting connection.
 
Thermoplastic
Hydraulok thermoplastic one piece fittings are manufactured from SS 316 stainless steel. Designed to work with SAE 100R7/100R8 hose in a variety of highpressure applications, Hydraulok thermoplastic hose fittings are easily assembled for crimping. The weather resistant thermoplastic hose cover combined with the non-corrosive attributes of the fittings create a flexible assembly for a range of conditions.
Hydraulok Thermoplastic hose fittings are often found in hydraulics systems, mobile equipment, and high pressure pneumatic systems.
Specifications & Operating Parameters
Standards & Approvals
SAE J517
Pressures
High. Up to 5,000 psi depending on hose construction and
fitting configuration.
Temperatures (limiting by the composition of the hose)
-40° to 200°F
Vibration
Medium to High. Depending on end fitting connection.
 
Metal
Hydraulok metal hose fittings are one piece designed fittings made from TSS 316L low carbon stainless steel with an integral
hex body. The hex provides a surface for applying a wrench during installation. This feature helps users avoid premature fatigue failure of the hose assembly caused by torquing the hose during installation.
The butt weld design features a tapered boss surface to provide ample surface area for welding filler material. The butt weld also has a significant wall thickness to avoid burning through the wall during welding.
Hydraulok Metal hose fittings are used with high pressure or low pressure flex metal hose frequently in extremely corrosive
environments for chemical or water transfer. It is also used in high temperature environments for low and medium pressure
hydraulics, and for liquid or gas transfer in cryogenic systems.
