Insert the tubing in to the preset system right up until it hits the bottom or shoulder on the Resource. Carry the flareless sleeve and tube nut right down to the preset tool and tighten the nut to the finger-limited situation.
Parker Ferulok fittings enable the fitting assembler to visually inspect the Chunk excellent, So considerably minimizing the risk of improper assembly and related service troubles.
Since the nut is tightened with the proper torque, the nut compresses the ferrule to the tube, So offering a robust and leak-free of charge seal. The higher the composition drive the bigger the required wall thickness of the tube and so more appropriate for flareless fittings. Thicker walled tubing isn't realistic or perhaps easy to flare.
The internal design and style of the human body causes the sleeve to crimp into your OD in the tube as the human body and nut are joined. You will find there's counter bore shoulder in the human body from the fitting having a reverse angle of fifteen° for metal connections, meant to prevent the tubing from an inward collapse when tightening and serves to be a sealing pressure towards the body from the counter bore.
Hy-Lok flareless Chunk style tube fittings are exclusively created for medium to significant wall tubing that may be tricky to flare. These solitary ferrule bite type fittings ...
The above illustration displays an assembly using the SAE "A" Model flareless sleeve. When assembled effectively the SAE "A"design and style flareless sleeve assembly will show the following features.
The midsection on the sleeve powering the top edge incorporates a slight bow to provide contact with The interior taper of your fitting body and kind a sealing issue.
The fitting system can be utilized just once for presetting and will be used all through last installation While using the preset tube line. The following steps are necessary for right preset of your ferrule using the fitting entire body.
Lubricate the threads on the preset overall body, tube nut, and periphery of both ends from the flareless sleeve.
All fittings On this portion are requested as assemblies only Except normally specified by customers when purchasing. (Get in touch with Entire world Broad Fittings when ordering fittings as bodies only or configurations which might be non-common.)
Flareless nuts have a grey look due to molly coating follow served to rise the program from the nut. All File series Flareless fittings are produced from 316 stainless steel.
The Ferulok bite form fitting is actually a flareless fitting that contains a human body, a one-piece precision machined ferrule, plus a nut. On assembly, the ferrule “bites†into your outer surface area with kp-lok.com the tube with sufficient power to carry the tube against stress, devoid of significant distortion of the inside tube diameter. The ferrule also varieties a pressure seal in opposition to the fitting overall body.
SSP SAE flareless or “Chunk type† tube fitting demonstrated structure has long been made use of around the world for over sixty several years in innumerable programs in the air, on floor, and at sea.
In lower to medium pressure programs, the most typical relationship type can be a flared fitting. One flare SAE 37° may be the typical in most hydraulic methods. SAE criteria for the most tube wall thickness has to be adopted in advance of flaring the tube to match the fitting relationship.Â
