Description

The BECA 014 profile is a polyurethane static seal. It provides an alternative solution to combining an O'Ring (possible twisting during fitting) with a back-up ring (positioning is not always optimal).

Advantages

Excellent resistance to twisting
Easy assembly
Excellent extrusion resistance

Materials

PU

Polyurethane is a material that has the elastic properties of rubber. The proportion in its composition (diisocyanate, polyol, chain extender) is determined by its properties. This material is characterised by a strong mechanical resistance, good wear resistance, high elastic modulus, good flexibility and a very good ozone and oxidation resistance.

Chemical resistance Pure aliphatic hydrocarbons (propane, butane)
Mineral oils and greases
Silicone oils and greases
Water up to +50°C
Compatibility issue Ketones, esters, ethers, alcohols and glycols
Hot water, steam, alkalis, amines and acids
Temperature range -30°C/+90°C
-30°C / +110°C with our PUHT (short term peak at 150°C)

Preferential extrusion gaps

The mechanical tolerances below are recommended for optimal operation:

  • Bore diameter: H8
  • Groove diameter: g6

A radial extrusion gap of F/2 at 0.20 mm is acceptable, depending on the shape of the seal and the type of material that makes up the seal.

Surface roughness

In static radial applications Ra µm Rt µm Rz µm
Contact surface area ≤ 1.6 µm ≤ 10.0 µm ≤ 6.3 µm
Groove diameter surface ≤ 3.2 µm ≤ 16.0 µm ≤ 6.3 µm
Groove flanks ≤ 3.2 µm ≤ 16.0 µm ≤ 6.3 µm
