STAUFF Heavy Series Clamp Body with Elastomer Insert Type RI

Description

Design and Operating Principle

The STAUFF Heavy Series Clamp Body with Elastomer Insert Type RI is specifically designed for the technical fastening of pipes and flexible hoses, providing vibration control and noise reduction in hydraulic systems. Each assembly consists of one clamp body and two elastomer inserts. This configuration, developed for the Heavy Series, is essential for applications requiring secure yet flexible retention of conduits while preserving the structural integrity of the system.

Construction Features and Materials

The robustness of the STAUFF Heavy Series Clamp Body with Elastomer Insert Type RI is ensured by the use of high-strength polymer materials. The clamp body is available in two standard variants, both black:

Polypropylene (Material Code: PP-R): provides an excellent balance of mechanical strength and chemical stability.
Polyamide (Material Code: PA-R): suitable for applications requiring superior mechanical performance and greater thermal tolerance.

The inserts, essential for absorbing mechanical stress, are manufactured from Thermoplastic Elastomer with a hardness of 73 Shore-A, also in black. This combination of materials prevents wear caused by direct friction between the pipe and the rigid clamp.

Dimensions and STAUFF Groups

The product is classified into two main dimensional groups, designed to accommodate specific outside diameters (OD):

STAUFF Group 4S-D: Designed for pipes with outside diameters from 6 mm to 19 mm (including imperial sizes such as 5/16″, 1/2″, 5/8″ and 3/4″). The structural dimensions of the clamp include an overall length (L1) of 115 mm, with a centre distance (L2) of 90 mm. The height (H1) is 48 mm, with a profile width of 30 mm and an accommodation diameter (ØD) of 25 mm.
STAUFF Group 5S-D: Intended for larger pipe sizes, with outside diameters ranging from 20 mm to 32 mm (including 7/8″ and 1-1/4″). The overall length (L1) increases to 145 mm, the centre distance (L2) to 120 mm and the height (H1) to 60 mm. It retains the same width of 30 mm, with an increased accommodation diameter (ØD) of 38 mm.

Coding and Ordering Specifications

Correct identification of the STAUFF Heavy Series Clamp Body with Elastomer Insert Type RI is achieved through a precise ordering code system. The complete Clamp Assembly is identified by codes ranging from 4006/06-**-R to 4019/19-**-R for Group 4S-D, and from 5020/20-**-R to 5032/32-**-R for Group 5S-D, where the asterisks indicate the selected material code (PP-R or PA-R).
